摘要: We demonstrate a six-channel tunable optical transmitter photonic integrated circuit fabricated in an open-access indium phosphide foundry process. The device monolithically integrates 20-nm lasers and 30-Gb/s Mach–Zehnder modulators, without the use of Bragg gratings or quantum wells for phase modulation, to form compact ${\text{3.9}} \times {\text{4.5 mm}}^{2}$ high-density $\text{6} \text{30}$ Gb/s parallel transmitter. It exhibits capacity density metric 10 Gb/s/ $\text{mm}^2$ , comparable state-of-the-art results from literature low $ dB inter-channel radio-frequency crosstalk. With attractive price point 7 USD/Gb/s, can be low-cost solution data center interconnects residential access networks.
