Abstract
Methods and systems for reducing dark current in a photodiode include heating a photodiode above room temperature. A reverse bias voltage is applied to the heated photodiode to reduce a dark current generated by the photodiode.
Claims12
A method for reducing dark current in a photodiode, comprising:
- heating a photodiode above room temperature;
- measuring the dark current generated by the photodiode;
- and
- applying a reverse bias voltage to the heated photodiode to reduce a dark current generated by the photodiode, increasing the reverse bias voltage until the measured dark current stabilizes to maximize a stable dark current reduction after the photodiode returns to room temperature.

A method for reducing dark current in a photodiode, comprising:
- heating a photodiode above room temperature;
- and
- applying a reverse bias voltage to the heated photodiode to reduce a dark current generated by the photodiode, increasing the reverse bias volatage until reductions in dark current halt.
