Abstract

Optical multiplexers and demultiplexers join together, and separate, light of different frequencies particularly so that they can be transmitted down a common optical wave guide. An element for use in a multiplexer or demultiplexer (shown) comprises a transparent dielectric substrate (60) and at least two transmission filters, (11, 12, 13, 14, 15, and 16) each of which transmits light of a predetermined wavelength and reflects light of other wavelengths. The optical filters are arranged so that an optical beam is transmitted or reflected via each optical filter in turn and in a zigzag fashion with light of a particular wavelength being subtracted or added at each filter in dependence of whether the element is being used as a demultiplexer or multiplexer. When the element is being used as a multiplexer a source of light is provided behind each filter and when the element is used as a demultiplexer a photosensitive detector (71, 72, 73, 74, 75 and 76) is provided behind each filter. <IMAGE>
