Abstract
A calibrate and run bias voltage control method for an optical delay system utilizing a plurality of voltage controlled switches which may experience bias drift wherein during calibration an output optical power error signal of the system is monitored while rapidly changing the bias voltages to the switches according to a desired algorithm and setting the bias voltages at a the level achieved when the output error signal falls below a predetermined tolerance level.
