20120213480 | CO-PACKAGED SEMICONDUCTOR OPTICAL DEVICES - A plurality of semiconductor optical devices has a common package and common supporting structures and controls. The semiconductor optical devices are typically semiconductor lasers or photodiodes and are designed for operation independently of each other or in a coordinated way. In one embodiment, co-packaged semiconductor lasers may be used individually to drive each of the amplification stages of a multi-stage optical amplifier. The optical fibers connecting to the optical devices share a common port and are aligned prior to engagement with the light output/input of the co-packaged semiconductor optical devices. | 08-23-2012 |
