Abstract
A GmAPD FPA having increased tolerance optical overstress includes a limit resistor that is monolithically integrated into each pixel in the FPA, and which limits the magnitude of the current entering the read out integrated circuit.
Claims18
A method of controlling a Geiger-mode avalanche photodiode (GmAPD) focal plane array (FPA), the method comprising:
- increasing, within each pixel of the GmAPD FPA, a series resistance of an electrical connection between the GmAPD and a unit cell of a read out integrated circuit (ROIC unit cell), the ROIC unit cell having an active quenching circuit.
A method of controlling a Geiger-mode avalanche photodiode (GmAPD) focal plane array (FPA), the method comprising:
- monolithically integrating, into each pixel of the GmAPD FPA, a limit resistor,
- wherein the limit resistor is electrically coupled in series to an electrical contact of the GmAPD and to an active quenching circuit within a unit cell of a read out integrated circuit (ROIC unit cell).
