20080285978 | OPTICAL HYBRID MODULE - Provided is an optical hybrid module in which an optical device, a filter, an amplifier and an antenna are hybrid-integrated, which includes: a silicon optical bench disposed on a substrate and having an optical fiber and an optical device; an amplifier disposed on the substrate and connected to the optical device disposed on the silicon optical bench to amplify a signal transmitted from the optical device; and an antenna disposed on the substrate to be connected to the amplifier and transmitting a signal amplified by the amplifier. Thus, a foot-print module may be embodied by disposing an antenna and a filter on a single- or multi-layer substrate and providing a bias required for the optical device and the amplifier through a solder ball. Also, due to the antenna and filter disposed on the substrate, an expensive connector is not needed, and thus a production costs can be reduced. | 11-20-2008 |
