Optical Material Studies (OM)

Optical Material Studies (OM)

This group is involved with the development and characterization of new and improved optical materials. Materials include those with superior transmission in the UV, visible near and mid-infrared portions of the spectrum for use in passive and active optical elements and devices as well as those having unusual nonlinear optical properties for use in switches and limiters. Examples of novel materials include quantum engineered multiple quantum wells for lasing, photonic structures with unusual properties (negative index, left-handed, highly nonlinear, etc.) and sintered ceramic materials displaying superior hardness, strength and transmission in the infrared.
 

Special Talk at Frontiers in Optics


The OSA Optical Material Studies Technical Group had a special networking event during lunch on Tuesday, 18 October, at Frontiers in Optics 2016 in Rochester, NY. Over 45 people attended the event which was to feature Professor Michal Lipson, Columbia University, speaking on the topic of Novel Materials for Next Generation Photonic Devices. Unfortunately Prof. Lipson was not able to attend at the last minute and the talk was given instead by her graduate student Chris Phare.

Chris gave a very interesting talk on silicon photonics, describing design and process improvements to lower loss of Si waveguides. He described the fabrication of Si waveguides on silicon nitride substrates and the smoothing of sidewalls to reduce scattering loss. He also described the transfer of graphene on top of a Si ring resonator to control its modulation and bandwidth. They demonstrated a 30 GHz modulator by this technique.  

 

Special Talk at OSA Advanced Photonics Congress

A special talk at lunch was given by Professor Craig Arnold (Princeton University) on “Silver Nanowire Network Transparent Electrodes for Organic and Hybrid-Organic Devices” organized by OSA Optical Material Studies Technical Group. It was a great introduction to the field of nanowire transparent electrodes. Dr. Arnold clearly explained the problem of the current electrodes, such as contact resistance, integration, and roughness. He then discussed his way to form the contact of silver nanowire electrodes by plasmonic resonant absorption. These silver nanowire transparent electrodes allow the possible replacement of current ITO transparent electrodes in flexible displays. [Advanced Functional Materials 25, 7428 (2015)].
 

Optical Material Studies Poster Session at CLEO: 2016


At CLEO 2016, held in San Jose from June 5-11, the Optical Materials Study Technical Group cohosted a networking event with 3 other technical groups, the Nanophotonics Technical Group, the Optoelectronics Technical Group, and the Optical Biosensors Technical Group. The event was held on the evening of Monday, June 6, with poster presentations from all the technical groups in one room. Snacks and drinks were provided by OSA for the attendees.



About 200 people attended the event and there were active and crowded discussions at all the posters. The attendees were given four chips so they could vote for the best paper in each technical group. There were nine posters from the Optical Material Studies Technical Group, with the presenters and titles listed below. The winner of the Optical Material Studies Technical Group poster award was Hiral Patel from Oregon State University.
