ABSTRACT:
Apparatus is provided for coupling the optical energy conducted through an optical fiber to an electro-optic hybrid element, such as a photodetector, that is positioned within a hybrid casing. The outer jacket of the fiber is stripped, cleaved to 45 degrees and silvered or coated with a dielectric to form a mirror for directing the optical energy through the side of the cladding. A window, transparent to a predetermined bandwidth of the optical energy, is provided in the lid of the case overlying the electro-optic element. The mirrored end of the fiber is positioned above the window and the element while the fiber is fixed to the top of the lid of the casing. The arrangement requires no ferrule and permits bakeout and testing of the hybrid package prior to engagement of the optical fiber.
