Abstract :
Optical amplification by stimulated emission is achieved in a vertical microcavity. A fast response of 20 ps and a gain of 2.5 dB point to an optical switch with a modulation width >10 GHz, capable of handling 2 THz signals. The sample studied is composed of an active medium of 130 period GaAs-Al0.3Ga0.7As multiquantum wells with 10 nm/10 nm nominal layer thickness sandwiched between a pair of Bragg reflector mirrors.
