摘要

Optical power dependence of capacitance in uni-traveling-carrier photodetectors is analyzed by founding a differential capacitance model. The trend of capacitance variation against optical power by simulation gets a good agreement with the measured results. The relationship between light-intensity-dependent capacitance and DC saturation characteristics of the device is also investigated at different collection layer thicknesses. The optical power at the maximum point of capacitance is near that at the DC saturation point. With the thickness of collection layer increasing, the maximum capacitance decreases and optical power at capacitance maximum point also becomes small.
