We demonstrate a six-channel tunable optical transmitter photonic integrated circuit (PIC) fabricated in an open-access indium phosphide foundry process. The device monolithically integrates 20 nm tunable lasers and 30 Gb/s Mach-Zehnder modulators, without the use of Bragg gratings or additional quantum wells, to form a compact 4×4.5mm2 high-density 6 × 30 Gb/s parallel transmitter. It exhibits a capacity density metric of 10Gb/s/mm2 , comparable to state-of-the-art results from literature and low <-50 dB inter-channel radio-frequency crosstalk. With an attractive price point of 7 USD/Gb/s the device can be a low-cost solution for data center interconnect or residential access networks.
