Popis: The externally applied bias operation of linear mode avalanche photodetectors (APDs) is extended and compared to single photon avalanche photodetectors (SPADs). The minimum bias required for linear operation is calculated using the effective voltage field in the photodetector through Mach-Zehnder modulator (MZM) interference which allows for quantifiable incident peak and dc optical powers. This mode of operation allows for a quantifiable minimum bias on the diode, may enable a dualuse for single photon detectors at higher optical powers, and ensures RF signal conversion.
