Abstract
Carrier heating of a semiconductor optical amplifier (SOA) using half-cycle terahertz pulses is investigated. For reasonable parameters, the electron- hole plasma temperature can be increased substantially. The subsequent chan ge in the refractive index and gain profile of the SOA is predicted to be l arge enough to form the basis of a very efficient ultrahigh-speed optical s witch.
