An integrated optical multiplexer and/or demultiplexer includes an integrate d circuit substrate (12) formed with an array of photo detectors (13, 14, 16 a nd 17) (for the demultiplexer) or photo emitters (for the multiplexer). Conditioning electronics (18) is formed on the substrate and is coupled to t he 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 secon d layers of optically transparent material.
