Microresonator solitons for massively parallel coherent optical communications [PDF]
Nature, 2017 Optical solitons are waveforms that preserve their shape while propagating, relying on a balance of dispersion and nonlinearity. Soliton-based data transmission schemes were investigated in the 1980s, promising to overcome the limitations imposed by ...

Modular coherent photonic-aided payload receiver for communications satellites
Nature Communications, 2019 Satellite communications shall only thrive if being able to compete with fibre in both bandwidth and cost. Here, the authors demonstrate that a coherent and yet modular photonic-aided payload is feasible, paving the way for a new generation of ...

Symbiotic joint operation of quantum and classical coherent communications [PDF]
Optical Fiber Communications Conference and Exhibition, 2022 We report successful joint operation of quantum and classical communications with shared hardware. Leveraging information learned from the classical DSP, low-noise quantum communications (0.009 SNU at 15 km) compatible with 15 Mbit/s QKD is demonstrated.

Model-Driven Deep Learning for Non-Coherent Massive Machine-Type Communications [PDF]
IEEE Transactions on Wireless Communications, 2023 In this paper, we investigate the joint device activity and data detection in massive machine-type communications (mMTC) with a one-phase non-coherent scheme, where data bits are embedded in the pilot sequences and the base station simultaneously detects
