Abstract
In a laser control arrangement for tuning a laser a portion of the optical signal exiting a resonator is directed to the input of an optical frequency routing device. The routing device has a plurality of outputs each for receiving one of the frequencies supplied by the laser. Each output is coupled to a photodetector. When the laser emits a frequency of light corresponding to one of the resonant frequencies of the resonator, the resonant frequency will appear on one of the outputs of the routing device and will be detected by the photodetector coupled to that output.
