Abstract
The effect of temperature on the transit time limited frequency response of p-i-n photodiodes is investigated. The temperature effects are embodied in the absorption coefficient, in the electron and hole mobilities and in the electron and hole saturation drift velocities. The numerical model is applied to devices with a linear electric field profile in the absorption region and non-uniform illumination. The results show, for a given reverse bias voltage, that the bandwidth decreases when the temperature increases.
