Ar. Williams et al., HIGH-FREQUENCY SATURATION MEASUREMENTS OF AN INGAAS INP WAVE-GUIDE PHOTODETECTOR/, Electronics Letters, 29(14), 1993, pp. 1298-1299
The high frequency saturation characteristics of an InGaAs/InP wavegui
de pin photodetector are measured. At a wave-length of 1.3 mum, the de
tector has a responsivity of 0.5 A/W and a flat frequency response fro
m 800 MHz to 20 GHz. With a bias of -4V, the normalised frequency resp
onse of the detector remains unchanged when optical powers up to 10 mW
are incident on the detector.
