ABSTRACT:
In accordance with the present invention, an optical device is provided which is used to lock the output of an optical transmitter as well as being employed as a self-filtering element within an optical system. An optical transfer element, coupled along the optical transmission path, either reflects or transmits a portion of the light signal associated with the desired channel wavelength. A portion of the optical signal is supplied to a circuit which controls the output of the transmitter.
