Overview: 

Silicon photonics provide a means to integrate optical waveguides and optical components on Si chips, resulting in stable photonic circuits that maintain phase coherence across the whole integrated system. Si photonics therefore enables the creation of complex systems of interferometers that can be controlled by on-chip phase shifters. In this talk we describe examples of such systems, with emphasis on laser manipulation of electrons. We cover the basics of electron-laser interactions and show how acceleration, focusing, and creation of ultra-short pulses of electrons can be achieved. We demonstrate experimental verification of 700 attosecond temporal resolution and show a path towards single-digit attosecond instrumentation.

Profile: 

Olav Solgaard earned his Ph.D. degree from Stanford University in 1992. His doctoral dissertation: “Integrated Semiconductor Light Modulators for Fiber-optic and Display Applications” was the basis for the establishment of a Silicon Valley firm Silicon Light Machines (SLM), co-founded by Dr. Solgaard in 1994. From 1992 to 1995 he carried out research on optical MEMS as a Postdoctoral Fellow at the University of California, Berkeley, and in 1995, he joined the Electrical Engineering faculty of the University of California, Davis. His work at UC Davis led to the invention of the multi-wavelength, fiber-optical switch, which has been developed into commercial products by several companies. In 1999 he joined Stanford University where he is now a Professor of Electrical Engineering and the Director of Graduate Studies in the Department of Electrical Engineering. Professor Solgaard’s research interests include optical MEMS, Photonic Crystals, optical sensors, microendoscopy, atomic force microscopy, and solar energy conversion. He has authored more than 350 technical publications and holds 75 patents. Professor Solgaard is a Fellow of the IEEE, the Optical Society of America, the Royal Norwegian Society of Sciences and Letters, and the Norwegian Academy of Technological Sciences.
