S. Charbonneau et al., HIGH-SPEED PHOTORESPONSE IN A REVERSE-BIASED INGAAS INP LASER STRUCTURE AT 1.54 MU-M - EXPERIMENT AND MODELING/, Applied physics letters, 63(1), 1993, pp. 12-14
We report extremely efficient (approximately 100% internal quantum eff
iciency) and high-speed (approximately 120 ps lifetime) photodetection
in a reversed biased InGaAs/InP ridge-waveguide multiple quantum well
p-i-n laser structure operating at 1.54 mum. The impulse response of
this monolithically integratable detector is analyzed in terms of the
escape of photogenerated carriers from the InGaAsP quantum well barrie
r to the InP cladding contact layer.
