Abstract :
A report is made on the temporal response of pin photodiodes, whose intrinsic region is a GaInAs/AlInAs weakly-coupled superlattice designed for 1.55 mu m photoreception. Their response time is shown to depend on the wavelength. The largest bandwidths (up to 22 GHz) are obtained with photon energies above the barrier material bandgap.
