We present an overview of Infinera's current generation of 100 Gb/s transmitter and receiver PICs as well as results from the next-generation 500 Gb/s PM-QPSK PICs.
In this work, a 10-wavelength, polarization-multiplexed, monolithically integrated InP coherent QPSK transmitter PIC is demonstrated to operate at 112 Gb/sec per wavelength and total chip superchannel bandwidth of 1.12 Tb/s. This demonstration suggests that increasing data capacity to multi-Tb/s per chip is possible and likely in the future.
The status and progress of InP photonic integration is reviewed. Infinera has previously reported on the manufacturing of 100 Gb/s InP-based large-scale photonic integrated circuits. These PICs, based on amplitude modulation and with more than 50 discrete functions per chip, have now reached a high level of manufacturing maturity, and have furthermore… (More)
