Abstract
An optical coupler comprising an optical chamber having a reflective wall. A light emitting device, such as an LED or the end of an optical fiber, is positioned adjacent to one end of the optical chamber. The end of a receiving optical fiber extends into the chamber from the opposite end thereof. A light transmitting filler fills the chamber so that light emitted into the chamber by the light emitting device will reflect off the chamber wall and impinge upon the outer surface of the receiving fiber. The receiving fiber is insensitive to alignment problems due to the close proximity of the reflector and receiver surfaces and the large receiving surface area.
