Extended C-Band Tunable Multi-Channel InP-Based Coherent Transmitter PICs

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.

Integrated line-by-line optical pulse shaper for high-fidelity and rapidly reconfigurable RF-filtering.

We present a 32 channel indium phosphide integrated pulse shaper with 25 GHz channel spacing, where each channel is equipped with a semiconductor optical amplifier allowing for programmable line-by-line gain control with submicrosecond reconfigurability. We critically test the integrated pulse shaper by using it in comb-based RF-photonic filtering experiments where the precise gain control is leveraged to synthesize high-fidelity RF filters which we reconfigure on a microsecond time scale. Our on-chip pulse shaping demonstration is unmatched in its combination of speed, fidelity, and flexibility, and will likely open new avenues in the field of advanced broadband signal generation and processing.

Extended C-Band Tunable Multi-channel InP-based Coherent Receiver PICs

Fully integrated monolithic, multi-channel InP-based coherent receiver PICs and transceiver modules with extended C-band tunability are described. These PICs operate at 33 and 44 Gbaud per channel under dual polarization (DP) 16-QAM modulation. Fourteen-channel monolithic InP receiver PICs show integration and data rate scaling capability to operate at 44 Gbaud under DP 16-QAM modulation for combined 4.9 Tb/s total capacity. Six channel simultaneous operation of a commercial transceiver module at 33 Gbaud is demonstrated for a variety of modulation formats including DP 16-QAM for >1.2Tbit/s aggregate data capacity.

System-on-Chip Photonic Integrated Circuits

Key advances which enabled the InP photonic integrated circuit (PIC) and the subsequent progression of InP PICs to fully integrated multichannel DWDM system-on-chip (SOC) PICs are described. Furthermore, the current state-of-the-art commercial multichannel SOC PICs are reviewed as well as key trends and technologies for the future of InP-based PICs in optical communications.

Comb-based programmable RF photonic filter with an InP arrayed waveguide grating pulse shaper

We demonstrate a comb-based programmable radio-frequency photonic filter which uses an InP arrayed waveguide grating pulse shaper for comb apodization. RF photonic filtering with high stopband attenuation of >36.4 dB is achieved with Gaussian apodization.
