Abstract
Conditions for the optimization of short pulse amplification and gating times in vertical cavitylaser amplifiers are elucidated using femtosecondphotoexcitation. The experimental results pertaining to the temporal response are analyzed by a theoretical model taking into account the carrier heating and the Fabry–Perot nature of the cavity. A 20 dB amplification gain is obtained in a vertical cavity structure at 1.53 μm with a capacity to function at a rate >25 Gb/s.Keywords
