ABSTRACT:
An optical multiplexer-demultiplexer comprises a one-piece support having three grooves arranged according to a T pattern to accommodate the stretched ends of three optical fibers to be coupled. A slit is arranged at an angle of substantially 45.degree. to the grooves and at the apex of the T pattern and contains a dichroic plate. The plate is made of a substrate carrying dichroic layers. The fibers are held in the groove by an index matching adhesive. The various members of the multiplexer-demultiplexer are assembled at the work site.
