Patent ID: 6963683

Claim:
An optical communication system, comprising: a receiving optical fiber device including an optical fiber core and optical fiber cladding; a point light source to generate and transmit a point light beam; and an optical subassembly adjacent to the receiving optical fiber device, including an interior surface of a first side to receive the point light beam and to create a convergent light beam, and a second side that the convergent light beam travels through to the receiving optical fiber device, wherein an exterior surface of the second side is positioned to create a wedge-shaped air gap to create an incident ray of the convergent light beam, the incident ray of the convergent light beam is directed to the interior surface of the first side of the optical subassembly to create a reflected light beam, and the reflected light beam travels through a third side of the optical subassembly, and the third side of the optical subassembly includes a lens attached to an exterior surface of the third side of the optical subassembly to direct the reflected light beam to a photodetector and to direct the point light beam to the interior surface of the first side of the optical subassembly.
