An integrated optical multiplexer and/or demultiplexer includes an integrated circuit substrate (12) formed with an array of photo detectors (13, 14, 16 and 17) (for the demultiplexer) or photo emitters (for the multiplexer). Conditioning electronics (18) is formed on the substrate and is coupled to the photo elements for conditioning electronic data for optical transmission in the case of the multiplexer or for conditioning optical signals into electronic data in the case of the demultiplexer. A first layer (22) of optically transparent material is formed on the substrate overlying the detectors and/or emitters and a second layer (23) of optically transparent material is formed on the first layer and functions as an optical waveguide. A binary blazed grating (23) is formed at the interface of the first and second layers of optically transparent material.
