Abstract
A semiconductor laser assembly is provided with a photodetector module and a laser module mounted on orthogonal surfaces of a heatsink. The photodetector module includes a photodetector and two electrically isolated wire bond blocks, each with two surfaces parallel to the orthogonal surfaces of the heatsink. The laser module includes a laser diode bonded and a wire bond region with two surfaces also parallel to the orthogonal surfaces of the heatsink. Both of the wire bond block surfaces of the photodetector modules are thus parallel to the wire bond region surfaces on the laser module, allowing wire connections to be made between parallel surfaces before the heat sink is mounted on a header. One of the surfaces of each of the wire bond blocks and regions is parallel to the pins of a header, allowing attachment of wires from the photodetector module and the laser module to the pins without rotating the header and pins.
