Abstract

A laser receptacle assembly used as a source in a fiber-optic communication system is comprised of a GaA1As or InGaAsP laser diode, a coupling lens, and a housing with an integral fiber-optic connector. The coupling efficiency of such a laser receptacle is the numeric ratio of the power launched into the core of the optical fiber to the total power emitted from the front facet of the laser, expressed as a percentage.
