Simulation results for the implementation of a high speed optical switch is presented. The optical switch uses a semiconductor optical amplifier with a pre-impulse-step injected current as the switching signal. The optical semiconductor amplifier may achieve less than 50 pico seconds off-on switching times. The simulated results have been partially confirmed using an experimental apparatus.
