1. A method, comprising:
directing a modulated optical beam to a test photodetector;
obtaining a modulation amplitude of a photo-signal associated with detection of a first portion of the modulated optical beam by the test photodetector;
based on the modulation amplitude of the photo-signal from the test photodetector, determining at least one first calibration coefficient operable to linearize the test photodetector; and
storing the at least one first calibration coefficient in a memory device.
