High-Speed All-Optical Switching

Abstract

A scheme for ultrahigh-speed all-optical switching based on semiconductor heterostructures was explored theoretically. The approach was anticipated to be applicable to systems operating in the 10 to 100 gigabit/sec regime. Our role was to simulate the carrier dynamics in semiconductor heterostructures under ultrafast (picosecond and subpicosecond) laser excitation. Pulse characteristics were found to coherently populate and depopulate the semiconductor heterostructure of carriers on the picosecond timescale.
