Devices for reflection reduction in optical devices

摘要

This invention describes an optical component incorporated in an optical device or subassembly for reducing reflections at the terminal end of an optical fiber. An optical device has a housing having an opening for receiving and securing a terminal end of an optical fiber. An optical component having a first facet and a second facet is positioned so that the first facet abuts the terminal end when the optical fiber is received in the opening. The optical component has a thickness that is chosen to be large enough that reflections from the second surface are sufficiently diverged to prevent substantial coupling back into the core of the optical fiber.
