You can get medicament to treat acute treatment of the symptoms of rheumatoid arthritis or cramp. Unconditionally most famous is Viagra. What about sexual health and women viagra and womens viagra? Like many other medicines, Viagra is classified according of it’s main ingredient. Also known as impotence is defined as the impossibility to maintain an hard-on suitable for intercourse. Is it dangerous? Of course. Multiple sclerosis can contribute to erectile malfunction. While the remedy is credited with nerve pain, it can also kill the mood in bedroom. Causes of erectile dysfunction include psychologic factors, such as nervousness over his ability to sexually perform.

First OSKar’s Poster Competition, Nov 2013

During the Karlsruhe Days of Optics and Photonics on 5th and 6th of November 2013, OSKar awarded five KSOP Ph.D. students for presenting impressive posters. The poster’s accessability and the oral presentation of the  Ph.D. students were rated by a panel of Master students. OSKar congratulates Robert Schittny, Andreas Merz, Michael Bachmann, Aleksandar Nesic and Felix Nickel as the winners in their KSOP research area. We would like to thank the Optical Society for supporting this event.

Talk on ‘Photonic devices in motion’

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 lightwaves, 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.

Biography: Mo Li is an assistant professor in the Department of Electrical and Computer Engineering at the University of Minnesota since 2010. From 2007 to 2010, he was a postdoctoral associate in Department of Electrical Engineering at Yale University. He received his Ph.D. degree in Applied Physics from Caltech in 2007. His awards include the AFOSR Young Investigator Award in 2012 and the McKnight Land-Grant Professorship in 2013.
