Subpicosecond All-Optical Switching of 1550 nm Signals in Hybrid Silicon:VO2 Waveguides and Ring Resonators

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate all-optical, subpicosecond switching in silicon photonics devices, using the femtosecond insulator-to-metal transition in vanadium dioxide as the driving mechanism for an in-waveguide modulator, and very low switching thresholds in a hybrid ring resonator.
