Several students and professors of different backgrounds and research areas attended the talk and were amazed by Professor’s Xu presentation. The main focus of the talk was on the improved imaging of a mouse’s brain by using 2 and 3-photon-absorption. Followed by the lecture there was a small meet up with food and drinks, where the attendees could talk to the Professor in a more relaxed atmosphere. We are very grateful to OSA and specially Professor Xu for this exciting event.


Fraunhofer Talk by Dr. Eilenberger, KIT – April 2016

On April 20th, OSKar invited Dr. Falk Eilenberger, from Fraunhofer IOF, to give a talk on applications on nano-optics. The talk was held in the lecture hall of Lichttechnisches Insititut (LIT), at the KIT. Our secretary, Orlando Torres introduced the speaker. This lecture gave rise to huge interest among the students. The most impressive part was the anticipation of the development of the future of optics, i.e. optics in a very small size down to the nano-scale.

Dr. Eilenberger’s talk gave our students a space for discussion about nanoscience. Nanoscience is not only the concern of optics, but also the focus of many other research directions. We can imagine that in the coming years, the applications in nano-optics and other branches of nanoscience will play a broader and more significant role in our life.


After the talk, our colleague in charge of public relations, Isabel Allegro, also interviewed some of the audience for feedback. The interviewees regarded this lecture as comprehensive and helpful. Our chapter will provide as more attractive activities as possible in the future.

Excursion to SICK AG, Waldkirch – January 2016

On January 27th, under the leading of Dr. Martin Lauer from the Institute of Measurement and Control Systems (MRT) at the KIT, a group of our OSKar members with other KSOP master students paid a visit to SICK AG. This company is located in Freiburg in Breisgau and has earned a reputation around Germany for its optical sensing technology.


The staff there guided us through their production line and logistics department, and gave us an introduction on the history and newly developed products of the company. Afterwards they made two presentations for us: one of them focused on the technical development of SICK’s products, and the other concerning mainly the career and job opportunities in the company. Through this visit, our students gained more knowledge on the optical sensing and its applications in security, communication and other fields.




Stammtisch at Karlsruhe Christmas-market – December 2015

DSC_0058Last week, OSKar organized the traditional Stammtisch at the Karlsruhe Christmas-market. OSKarians and friends got together to enjoy the Christmas spirit and the typical food and drinks of this time. We also organized a small “treasure hunt” in order for everyone to get to know the different stands of the Christmas-market.

Excursion to Agilent, Waldbronn – November 2015

On November 20th 2015, OSKar organized an excursion to Agilent, Waldbronn. Docents of our members took part in this event, and got more insights about the company’s development status, researching projects and manufacturing facilities.


Several sessions of introduction presentations were given by the company’s senior managers, engineers and research scientists. Through their talks, our members had the opportunity to view the worldwide technical giant from different aspects. The presentation was followed by a visit to the producing department, where the engineers introduced Agilent’s product lines and ultra-clean rooms in more details.



The final part of the excursion was a group discussion between the staff of Agilent and our OSKar members. The former shared quite a lot of experience in engineering, research and career planning, which made the whole excursion perfectly fruitful.




IONS Karlsruhe – June 2015

OSKar was delighted to host the IONS Karlsruhe 2015 conference. This International OSA Network of Students conference brought together optics students from around the world, mostly PhD and Master students working in the field of optics and photonics. The organization committee consists of people from more than 10 different countries who came together to organize this scientific conference. The goal of the organizers was to give participants the opportunity to establish unique and worldwide contacts, have scientific and educational discussions with companions and professionals, open new horizons and gain essential knowledge in variety of research fields in Optics.

The conference was accompanied by the networking session and several social activities to stimulate an exchange between the participants beyond the scientific level and to enable intercultural networking, one of the main objectives of IONS Karlsruhe 2015.

Besides the scientific and social program, OSKar arranged a photo competition devoted to the International Year of Light 2015. Since this part of the conference was intended as an outreach project towards the general public, it was held in Karlsruhe’s main train station. In addition to the outreach aspect, the exhibition at the train station gave us the opportunity to welcome our participants at the point where they reached the city first.

The organization of IONS Karlsruhe 2015 was a tremendous effort by our whole student chapter, but it also resulted in very rewarding three days. The feedback from the participants has been unequivocally positive. Despite the work, we would love to repeat organizing a conference like this again in the future, because we think it can be an important experience of every young researcher’s life. The experience gained in terms of project management, intercultural communication, time-management and the volunteering for a professional society are invaluable.




Excursion to TRUMPF, Ditzingen – February 2015

On February 3rd, an excursion to TRUMPF was organized by OSKar, where participants had an opportunity to get insights about the company’s manufacturing facilities and interact with professionals.

The introduction presentation served well with the company’s history, worldwide collaborations and production facilities. The presentation was followed by excursion to the work-stations where entire manufacturing process was explained and an introduction to the laser cutting and punching machines was also made. The excursion was concluded with technical information about EUV lithography and different programs offered for students and entry level professionals to gain a fruitful experience.

SPIE Visiting Lecturer Lorenzo Pavesi, about Silicon Photonics – October 2014

It was a pleasure for OSKar to welcome Professor Lorenzo Pavesi from the University of Trento on the 27th of October.

Talk on ‘Photonic devices in motion’ – November 2013

Mo-newAs a part of OSA’s travelling lecturer program, OSKar organised a talk on 12th November 2013.

Title        –  Photonic devices in motion
Speaker –  Prof. Mo Li, University of Minnesota

Abstract: Even in a simple optics experiment, mirrors, lens and lasers have to be moved around to align and adjust to make the optical system operational. In integrated optical devices, however, every optical component is carved into the semiconductor or glass substrate. Thus their optical functions can hardly be changed, despite there is need to control their properties. In this talk, I will present several different ways to move integrated photonic devices to order to reconfigure their functions, to achieve high precision measurement of minute forces and to couple RF and microwave signals with light. We first demonstrate moving integrated waveguides by using forces generated by light on a silicon chip to excite the device’s mechanical vibration. We experimentally prove the theoretical prediction that this new optical force is bipolar – its direction can be tuned to be attractive or repulsive by changing the relative optical phase of coupled light waves, resembling the Coulomb force between positive and negative charges. We show the exploitation of optical forces in a variety of interesting optomechanical structures, including photonic crystal, micro-disk optical resonators and cavity optomechanics, and applications in advanced sensing and optical communication. Second, we will show that gigahertz surface acoustic waves (SAW) can be excited on the surface of integrated photonic devices build on piezoelectric substrates to interact with light strongly. This leads to a new category of piezo-photonic device with potential applications in RF/microwave photonics. Finally, we will demonstrate processes to transfer photonic devices onto plastic substrates to make them mechanically flexible and tunable.



Excursion to Helmholtz Institute of Microstructure Technology – October 2013

OSKar organised an excursion to one of the Helmholtz Institutes in Karlsruhe, IMT for the new KSOP intake of 2013 in October 22nd, 2013.  Institute of Microstructure Technology (IMT) is to accomplish research and development in the fields of microstructure and microsystems technology as well as bordering nanotechnology and sciences in general. More than 25 students participated in this excursion and experienced the latest development in the field of nano and microstructure technology. PhD students showed around the large variety of manufacturing processes, test methods, and state-of-the-art equipment for lithographic structuring (electron beam lithography, deep X-ray lithography, and UV lithography) and replication methods (hot embossing, thermoforming, and nanoimprint). Students were fascinated with the large and exotic clean-room facilities. The excursion was finished with drinks and pretzel.


Visit to Leica – July 2013

OSKar, along with support from KSOP, organized a visit to the German lens manufacturing giant, LEICA on 10th July 2013. Leica’s factory at Solms is one of its biggest lens manufacturing units with capabilities to produce the complex lens units for its M9 series cameras. About 20 students from KSOP had the opportunity to witness the whole lens manufacturing process starting from the grinding of lenses until their final assembly into cameras.

Invited Guest Lecturer: Dr. James Bergquist – November 2010

In November 2010 our chapter was happy to welcome Dr. James Bergquist from the National Institute of Standards and Technology (NIST) in Boulder, Colorado. We had invited Dr. Bergquist, who had received an OSA Travelling Lecturer award, to hold a talk on the topic of “Single Atom Optical Clocks” in the framework of the Friday Colloquium of the Faculty of Physics. Dr. Bergquist has worked in this field since finishing his PhD thesis in the group of Nobel laureate John Hall. His work has been recognised by numerous prices and recommendations ever since then.

His two-day visit encompassed tours of KIT’s Institutes of Applied Physics and Microtechnology, the ANKA synchrotron and the Nanoscribe GmbH, a local start-up company marketing laser lithography systems. On the second day of his visit we had a get-together with him and our faculty advisor Prof. Dr. Kurt Busch over lunch. Later an open and informal discussion between Dr. Bergquist, OSKar’s members and local students over coffee and cookies took place. Everyone was delighted by the presence of such a renowned scientist as Dr. Bergquist and took the opportunity to ask him about a wide range of topics including but not limited to his experiments in fundamental and high-precision science, career paths in science and his views and opinion on the different ways science is done around the world.

His talk, the highlight of his visit, followed this event. Professors, scientists, PhD students and undergraduate students filled the Lehmann auditorium to the brim. Dr. Bergquist then gave an account of how the techniques of optical cooling and entanglement in combination with cutting-edge equipment and thorough experiments can be harnessed to build one of the most accurate clocks in the world. Moreover, he described how this extremely precise clock can be used to make fundamental tests of basic physics.

We very much enjoyed the opportunity to meet a scientist with such a high standing as Dr. Bergquist and benefitted strongly from his input. Upon having returned to the USA, Dr. Bergquist wrote to us that he couldn’t recall to have ever been treated this nice. His visit also convinced us to hold more events with OSA’s Travelling Lecturers.

Optics Visualized Contest – June 2010

Our Optics Visualized Contest 2010 was held during the OSA Optics and Photonics Congress in Karlsruhe with its finale on 24th June 2010. The aim of this contest was to illustrate, instruct and promote concepts and phenomena in optics to the general public. We received more than thirty contributions from all over the world. Through the finale with a celebrated jury of Prof. Garmire (former OSA president) et al, a top price of two thousand dollars, as well as three others, was awarded out of the seven funny, inventive and thoughtful contributions presented. Prof. Haensch, Prof. Townes, Prof. Leuthold and many attendees of the congress also witnessed this event. OSKar received appreciation from OSA, contributors and attendees for organizing this contest. For more information and the contest results, please visit the contest’s home page.

IONS-Germany Berlin – June 2010

Our presence in IONS Berlin was the chance to introduce ourselves as a new conformed OSA Student chapter from Karlsruhe.
The activities included lab tours in the HU Berlin, TU Berlin, U Potsdam, Max Born Institute, as well as a presentation of all the attendant chapters. But it was not all about academics, our agenda also included a grill, sight seeing and boat tour in Berlin and a very remarkable guided tour through Potsdam. Our hosts in Berlin were very warm and made our stay in Berlin nice and instructive. We are looking forward to meet the other chapters again at the upcoming IONS!

Internship Icebreaker – April 2010

With the idea of giving the optics students a direct opportunity to contact companies in the field, we created the “Internship Icebreaker”.
In a very professional environment, representatives from selected companies in the field of optics and photonics expose the internships and master’s possibilities within their departments, while the students introduce themselves and directly enquire according to their interests.After our first intership icebreaker, we got very positive feedback from both parts: companies and students. On one side, the students established contacts that facilitated their selection for further internship positions, and on the other side the companies had the opportunity to get to know the applicants in a direct, formal and organized manner.
For this reason we have adopted the “Internship Icebreaker” as one of our regular events and it will take place once per year.
