ABSTRACT:
A wavelength division multiplexing optical communications system and components thereof capable of using as many as 10.sup.4 channels are described. The system uses a waveguide resonator which is evanescently coupled to an optical fiber or waveguide. There is also an intracavity element optically coupled to the waveguide resonator and the control circuit element which is capable of tuning the frequency of either the intracavity element or the waveguide resonator, or both, to specific frequencies. There may be a plurality of devices optically coupled to each other through the system waveguide to form an optical communications system.
