The capability of mounting a parallel-optical module onto a PCB through solder-reflow process contributes to reduce the number of piece parts, simplify its assembly process, and minimize a foot print for both AOC and on-board applications. We introduce solder-reflow-capable parallel-optical modules employing 1060-nm InGaAs/GaAs VCSEL which leads to the advantages of realizing wider modulation bandwidth, longer transmission distance, and higher reliability. We demonstrate 4-channel parallel optical link performance operated at a bit stream of 28 Gb/s 231-1 PRBS for each channel and transmitted through a 50-μm-core MMF beyond 500 m. We also introduce a new mounting technology of paralleloptical module to realize maintaining good coupling and robust electrical connection during solder-reflow process between an optical module and a polymer-waveguide-embedded PCB.

We introduce solder reflow-capable high-density parallel-optical modules for >100 Gb/s optical interconnects. Polymer-waveguide-coupled parallel-optical modules are also introduced with a unique mounting technology. 1060-nm 28-Gb/s InGaAs/GaAs VCSEL realizes a good signal quality at high temperature and error free for MMF transmission beyond 500m.

... Moreover, to fulfill the ever-increasing demand for reducing network power consumptions, the optical interconnect is now the most efficient solution for it [2]. Such optical links will be constructed with optoelectronic devices like vertical cavity surface emitting laser (VCSEL) [3], PIN photodetector (PIN-PD) [4], etc. Among them VCSEL is the most utilized transmitting devices for short distance (less than 300m) optical interconnects [5] due to its benefits of low power consumption, high modulation speed, and high coupling efficiency to multimode fiber etc.. To further increasing integration level at the fiber end, some attempts of integrating transmitting and receiving functions into only one chip, based on VCSEL structure, have been made. ...
