Photodiode DC and microwave nonlinearity at high currents due to carrier recombination nonlinearities

We present photodetector compression measurements to demonstrate the consequences of absorption in undepleted regions close to the depletion region of p-i-n photodiodes. This absorption can modify the frequency response of photodetectors operating above a few milliamperes. The frequency response sho...

Zusammenfassung:We present photodetector compression measurements to demonstrate the consequences of absorption in undepleted regions close to the depletion region of p-i-n photodiodes. This absorption can modify the frequency response of photodetectors operating above a few milliamperes. The frequency response shows power dependence and additional ripple and rolloff.
