An all-optical switch using intersubband transition in wide-gap II-VI-based quantum wells in an improved waveguide structure is presented. The waveguide exhibits a separate confinement heterostructure (SCH) and submicron high-mesa waveguide for stronger optical confinement. A reduction of 39% is achieved in control pulse energy for a 10 dB switching extinction ratio while maintaining a subpicosecond response.
