Manipulating Light on Chip


Prof. Michal Lipson

Cornell University, Ithaca, New York, USA


On-chip photonics could enable a platform for monolithic integration of optics and microelectronics for applications of optical interconnects in which high data streams are required in a small footprint. This approach could alleviate some of the current bottlenecks in traditional microelectronics. In this talk I will review the challenges and achievement in the field of Silicon Nanophotonics and present our recent results. Using highly confined photonic structures, much smaller than the wavelength of light, we have demonstrated ultra-compact passive and active silicon photonic components with very low loss. The highly confined photonic structures enhance the electro-optical and nonlinear properties of Silicon. We demonstrated several active GHz components including all-optical and electro-optic low power switches and modulators on silicon. Recently we have also demonstrated the first optical link on chip transmitting GHz data.



Michal Lipson is an Associate Professor at the School of Electrical and Computer Engineering at Cornell University, Ithaca NY. Prior to this appointment, she was a postdoctoral associate at the Department of Material Science and Engineering at MIT, following her Ph.D. in Physics at the Technion-Israel Institute of Technology. Her research focuses on novel on-chip Nanophotonics devices. She holds several patents on novel micron-size photonic structures for light manipulation, and is the author of over 100 technical papers in journals in Physics and Optics.
