Abstract

We demonstrate all-optical modulation via ultrafast optical carrier injection in a GaAs photonic crystal cavity using a degenerate pump-probe technique. The low switching(absorption) energy~120 fJ(10 fJ), and fast response(~15 ps), limited only by carrier lifetime, suggest practical all-optical switching applications.
