In this paper, the current state of the art for large-scale InP photonic integrated circuits (PICs) is reviewed with a focus on the devices and technologies that are driving the commercial scaling of highly integrated devices. Specifically, the performance, reliability, and manufacturability of commercial 100-Gb/s dense wavelength-division-multiplexed… (More)
A 10-wavelength, polarization-multiplexed, monolithically integrated InP transmitter PIC is demonstrated for the first time to operate at 112 Gb/s per wavelength with a coherent receiver PIC.
A 250Gb/s super-channel using Photonic Integrated Circuits (PIC) was transmitted over 6000km along with a 500Gb/s super-channel and conventional 40Gb/s and 100Gb/s channels. The linear terrestrial line system uses FlexWSS multiplexing technologies and Hybrid RamanEDFA amplifiers.
We report the first demonstration of a large-scale InP-based transmitter photonic integrated circuit (PIC) capable of 10-channel × 40 Gb/s per wavelength polarization-multiplexed RZ-DQPSK modulation.
We report on the current state of large-scale and high functionality photonic integrated circuits on the InP platform for transmitters, receivers, and other device applications.
We present real-time polarization mode dispersion (PMD) tolerance measurement results with a commercially available 500 Gb/s coherent modem. The first- and second-order PMD space is explored, showing that peak values of 500 ps of static, first-order PMD (differential group delay) have small penalties. The system was stressed using fast scrambling, with… (More)
We demonstrate a fully integrated multi-channel InP-based coherent transmitter photonic integrated circuits (PICs) with extended C-band tunability, operating at 33 and 44 Gbaud per channel under 16-QAM dual-polarization modulation. PICs are demonstrated integrating up to 14-channels enabling multi-Tb/s total PIC capacities.
In this paper we review recent developments in the area of receiver photonic integrated circuits for the implementation of polarization multiplexed (differentially coded), quadrature phase shift keying (DQPSK) transmission formats.
We demonstrate a 10 wavelength, 200 GHz spaced, monolithically integrated, polarization-multiplexed, InP differential quadrature phase shift keying receiver operating at 45.6 Gb/s per wavelength. The receiver is based on a novel technique for polarization demodulation and phase tracking that does not require any external components.
Super-channels promise high-bandwidth transmission while decoupling channel capacity from baud rate. Photonic Integrated Circuits (PICs) are optimal for delivering super-channels at over 100 Gb/s, with flexibility in modulation format, baud rate, dispersion tolerance, and reach.
