ABSTRACT:
A three dimensional star coupler for interconnecting a first bunch of optical waveguides such as fibers to a second bunch of optical waveguides or optical fibers characterized by a mixing element being a planar waveguide having a thickness approximately equal to the fiber diameter and having input and output surfaces coupled to the incoming and outgoing fibers which are all supported in the same plane. The mixing element consists for example of an elongated rectangular plate but also can have a configuration of arcs of a circular configuration.
