A tunable light source with narrow linewidth, small size and low power consumption is necessary for high-speed digital coherent communication system. We have developed a monolithically integrated n…
800G Ethernet is expected to be the dominant solution for the next generation inter- and intra-data-center connections. To boost the transmission capacity to 800 Gb/s, utilizing multi-level pulse a…
Characterization of the thermo-optically tuned multi -channel interference widely tunable semiconductor laser for quasi-continuous tuning is demonstrated for the first time. The characterization st…
