ABSTRACT:
An optical multiplexer is disclosed which comprises three waveguides, one for admitting or emitting light and two for receiving light. Each waveguide has an end face. One of the receiving waveguides has an optical layer on its end face which is disposed at an angle to the optical axis of that waveguide. The waveguides are juxtaposed so that their optical axes intersect substantially at the end face of the one receiving waveguide. The optical layer transmits part of the light into the one receiving waveguide. The remainder of the light is reflected into the other receiving waveguide. The intervening space at least partly bounded by the end faces of the waveguides have an index of refraction different from the waveguides themselves.
