Events Hosted by the Optical Material Studies Technical Group
Panel Discussion on Emerging Optical Materials
On Wednesday, 26 July 2017, the Optical Material Studies Technical Group hosted a panel discussion on the topic of ‘Emerging Optical Materials: Perovskites, 2D Optical Materials and Nanocolloids’ at the Novel Optical Materials and Applications Topical Meeting (NOMA) in New Orleans. The distinguished panelists were
Prof. Barry Rand of Princeton University, Prof. Christian Klinke from the University of Hamburg, Prof. Parag Deotare from the University of Michigan, and Dr. Pelayo García de Arquer from the University of Toronto.
Approximately 35 conference attendees participated in the lunch discussion moderated by Garo Khanarian, who serves as chair of the technical group.
The panelists each gave a 10 minute review of their work and then there was a lively Q&A and discussion. The topics ranged from metal halide perovskites for LED devices, perovskites quantum dots for light emission in the visible and near IR, role of excitons in 2D layered materials and interfaces, and electric field effects in 2D layer materials.
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.
