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 …

In order to overcome the capacity limitations of current lightwave systems based on the
single-mode optical fiber, massively parallel transmission in the spatial domain [space …

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 …

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

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 …

We report world record high data transmission over standard optical fiber from a single
optical source. We achieve a line rate of 44.2 Terabits per second (Tb/s) employing only the …

Spectral efficiency (SE) is one of the key metrics for optical communication networks. An
important building block for its maximization are optical superchannels, channels that are …

Since its early commercial deployment in the late 1980s, optical fiber has evolved to become
the predominant carrier of the globe's communications. Yet, after accommodating the world's …

We demonstrate the transmission of 10-GBd polarization-multiplexed probabilistically
shaped 16384-ary quadrature amplitude modulation (16384-QAM) over 25.5-km standard …

The stationary statistical properties of independent, identically distributed (iid) input symbols
provide insights on the induced nonlinear interference (NLI) during fiber transmission. For …
