Revisiting Probabilistic Constellation Shaping in Short-Reach IM-DD Systems

26th Optoelectronics and Communications Conference, 2021
Short-reach IM-DD links usually have no optical amplifiers and are subject to the peak-power constraint imposed by transmitter components. We revisit probabilistic constellation shaping in such IM-DD systems by answering several puzzling questions.

Basis Precoding Based on Probabilistic Constellation Shaping in QAM/QNSC

International Conference on Optical Network Design and Modelling, 2023
Quantum noise stream cipher (QNSC) is a physical-layer encryption approach for optical communications, and its security barrier is the "basis" that is used as the secret-key for symbol encryption. Regarding the fact that the basis is actually transmitted
