Abstract :
The authors have experimentally determined Auger recombination rates in compressively strained In/sub x/Ga/sub 1-x/As/InGaAsP/InP MQW lasers for the first time. The Auger recombination rates were derived from the measured turn-on delay times during large-signal modulation of single-mode lasers. The Auger coefficient increases from 5+or-1*10/sup -30/ to 13+or-1*10/sup -30/ cm/sup 6/ s/sup -1/ as the indium composition in the quantum well active region, x, increases from 0.53 to 0.73.<>
