Abstract :
Using a 2D physical model we present a theoretical study of the parameters that affect the saturation condition of an MSM photodiode (PD) under high optical power at 1.55 μm wavelength modulated with 40 GHz. We also report that, with an MSM operating at 40 GHz, we can expect a saturation limit with a maximum microwave power of 17 dBm due to space charge effect
