Celebrating the 20^ th anniversary of Optics Express, this paper reviews the evolution of
optical fiber communication systems, and through a look at the previous 20 years attempts to …

The ever-increasing data rate demand for wireless systems is pushing the physical limits of
standalone radio-frequency communications, thus fostering the blooming of novel high …

Micro-combs-optical frequency combs generated by integrated micro-cavity resonators–offer
the full potential of their bulk counterparts, but in an integrated footprint. They have enabled …

Fiber nonlinearity is one of the major limitations to the achievable capacity in long distance
fiber optic transmission systems. Nonlinear impairments are determined by the signal …

Abstract Photonic generation of Terahertz (THz) carriers displays high potential for THz
communications with a large tunable range and high modulation bandwidth. While many …

Data rates in optical fiber networks have increased exponentially over the past decades and
core-networks are expected to operate in the peta-bit-per-second regime by 2030. As …

We review probabilistic constellation shaping (PCS), which has been a key enabler for
several recent record-setting optical fiber communications experiments. PCS provides both …

A transmission system with adjustable data rate for single-carrier coherent optical
transmission is proposed, which enables high-speed transmission close to the Shannon …

A new coded modulation scheme is proposed. At the transmitter, the concatenation of a
distribution matcher and a systematic binary encoder performs probabilistic signal shaping …

This tutorial paper provides a foundation for integrating probabilistic shaping (PS) and
forward error correction (FEC). A layered PS-FEC architecture consisting of a PS encoder …
