Patent ID: 10243324

Abstract:
An apparatus providing a phase-matched interface between a driver device and a multibeam optoelectronic device, such as a VCSEL array device, is disclosed as well as various methods for utilization and manufacturing of the same. The interface device includes an input adapted to interface with the driver device, an output to interface with the multibeam optoelectronic device, and a power splitter to electrically connect the output to the input. The output includes a plurality of output contacts that each interface with one optoelectronic device among the plurality of optoelectronic devices of the multibeam optoelectronic device via one transmission line among a plurality of transmission lines having a common electrical length. In embodiments, the power splitter is a resistor-based power splitter that adjusts an overall impedance of the power splitter at each “tee” junction or intersection to provide an impedance-matched interface.
