M. Constant et al., DYNAMIC CHARACTERIZATION OF PHOTODETECTOR S PRODUCED USING III-V SEMICONDUCTORS WITH A PICOSECOND LASER, Annales de physique, 20(2), 1995, pp. 77-79
The purpose of this work is to use a picosecond laser to study the dyn
amic characteristics of photodetectors fabricated with III-V materials
. Measurements have been carried out on an interdigitated InAlAs/InGaA
s/InP Metal-Semiconductor-Metal (MSM) photodiode and an interdigitated
InGaAs/InP photoconductor. A comparison between the impulse response
of the photoconductor and the one of the MSM photodiode has been discu
ssed in terms of cut-off frequencies of these two devices.
