Abstract(in English) A compact, large-scale integrated Si optical I/O chip is a very promising candidate for an optical interconnections used in next-generation HPC systems and high-end servers. For a Si integrated optical I/O chip, a use of wavelength division multiplexing (WDM) technology is very attractive to increase the aggregated bandwidth. In this study, we developed a four channel integrated Si hybrid laser array for wavelength-tuning-free Si transmitter. We adopted common RR wavelength filters to define a highly uniform wavelength grid. In order to obtain a high output power, a four-channel SOA array chip was collectively bonded on to the Si mirror chip using a precise flip-chip bonding technology. The fabricated laser array has a compact chip size of 1.1×1.8mm. It exhibited a 4ch lasing at a uniform wavelength spacing of 12±0.5nm which was equal to the FSR of RR. Under 4ch simultaneous operation, we also obtained a high output power of >+5dBm/ch and high SMSR of >38dB.
