Our suggested VCSEL array optical subassembly (OSA) for 120 Gb/s-level parallel optical interconnect modules was composed of a 12 channel VCSEL array chip, a SiOB, two silicon spacers, and a molded microlens with accurate guide pin holes. For high speed operation above 10 Gb/s per a channel, we carefully designed transmission lines on the SiOB. The results of the transmission lines were measured as...
We propose a chip-to-chip optical interconnection using a silicon (Si) subcarrier integrated with a long-wavelength vertical-cavity surface-emitting laser (LW-VCSEL) array. As the basic study of that, we examined the microwave and optical characteristics of the Si subcarrier. Finally, a demonstrator that mounted the four channels and 1550-nm LW-VCSEL array on the subcarrier has been shown with no...
