Abstract

An efficient wavelength multiplexer/demultiplexer includes a plurality of 2x2 optical couplers (122, 180, 200, 220), each having a pair of matched gratings (130, 142; 182, 184; 202, 204; and 222, 224), having bandpass wavelengths (.lambda.1, .lambda.2, .lambda.3, .lambda.4), respectively, attached to two of the ports. An input signal (116) enters a port (120) and is split and reflected off the gratings (130, 142) and then recombined so as to provide all the input signal (116) at an output port (150) and no reflection out of the port (120). Another input signal (154) is incident on the grating (142) which is passed by the grating (142) and is coupled onto the output port (150) with the signal (116) as a signal (160). A similar arrangement exists for the other couplers (180, 200, 220) connected in series, each of which adds another input wavelength. Alternatively, in a de-multiplexing application the signal (116) may be broadband and the signals (154, 190, 206, 230) would be separate output wavelengths.
