ABSTRACT:
Square cross section optical fibers are accurately positioned for coupling light from laser diode emitting facets through a fiber lens. The fibers are placed in parallel channels formed in a photolithographic layer on a planar surface of a substrate and constrained in place by a retention plate. The fibers extend beyond the retention plate unrestrained by photoresist but overlying the exposed portion of the planar surface of the substrate. The fibers over the exposed portion are cemented in place and the photoresist layer is then removed leaving the constrained portion of the fibers in very accurately defined positions, and free of epoxy cement, for abutment to the familiar fiber lens.
