Highly-Sensitive Ultrafast Pulse Characterization Utilizing Four-wave Mixing in an Amorphous Silicon Nanowaveguide

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate frequency-resolved optical gating using four-wave mixing in a hydrogenated amorphous silicon nanowaveguide. The ultrahigh nonlinearity and the wide conversion bandwidth of this device allow characterization of sub-ps pulses with high sensitivity.
