ABSTRACT:
An optical coupling system couples an optical fiber to an optical semiconductor device. A beam expander is disposed within the optical semiconductor so as to receive light from or transmit light into the optical fiber. The coupling is accomplished by disposing a layer of an index matching gel or epoxy on either surface of the semiconductor optical device or the end portion of the optical fiber and another layer of an antireflective material adjacent to the index matching gel or epoxy. The semiconductor device may include an array of optical devices, each coupled to a corresponding optical fiber via the arrangement that comprises the index matching gel and the antireflective material. The semiconductor device may also include an array of waveguides, each configured to receive light from a corresponding optical fiber.
