ABSTRACT:
An optical pigtail assembly is described wherein the focusing lens through which the laser diode output passes has its planar surface facing the laser instead of its convex surface. This configuration provides greater coupling efficiency when launching 850 nm light from the laser into an optical fiber. In the method of manufacturing the optical pigtail assembly, ultraviolet, UV, cured epoxy is used to bond the elements of the pigtail assembly together. The use of UV cured epoxy overcomes environmental problems and high capital equipment costs associated with other types of laser pigtail assembly manufacturing methods.
