High optical power nonlinear dynamic response of AlInAs/GaInAs MSM photodiode

In this paper, we introduce a theoretical study and a numerical simulation of the nonlinear electrical response, including the harmonic-generation rate calculation, of an MSM AlInAs/GaInAs photodiode under high-illumination conditions. We also report that, with an MSM operating at 20 GHz, we can expect a saturation limit at a maximum modulated optical power as high as 100 mW.>
