Abstract :
Careful measurements of the OIP3 in high power photodetectors show a resonance peak at a particular bias voltage and photocurrent combination. In fact, for a given photocurrent, there exists an optimum bias voltage that maximizes the OIP3. One can envision a DC control circuit that would be able to maintain the optimum OIP3 performance from the photodiode. By optimizing the bias voltage for a given photocurrent, a peak OIP3 of +65dBm was measured which is believed to be the highest reported value to date.
