Increasing bandwidth requirements have posed significant challenges for traditional access
networks. It is difficult for intensity modulation/direct detection to meet the power budget and …

Probabilisticshaping is, nowadays, a pragmatic and popular approach to improve the
performance of coherent optical fiber communication systems. In the linear regime, the …

Multi-band transmission is one of the key practical solutions to cope with the continuously
growing demand on the capacity of optical communication networks without changing the …

A flexible coherent passive optical network (FLCS-CPON) is a promising solution for the
future access network. By offering increased speed, sensitivity, and flexibility, it enables …

The enhanced remote area communication (eRAC) scenario is an important growth point in
the communication market. In some remote areas where optical fiber access cannot be …

We demonstrate the 1,600-km transmission at nearly 1-Tb/s/λ signals with a capacity of 21.5
Tb/s. Probabilistic shaping was newly applied to high-speed coherent optical Nyquist pulse …

Sequence selection (SS) potentially offers a pragmatic way to unlock nonlinear shaping
gains in coherent optical fiber communications beyond those offered by probabilistic …

This paper analyzes the distribution characteristics of crosstalk in a phase-coded
multiplexed collinear holographic storage system and realizes an optical router by this …

In this paper, the pre-and post-equalizers of all subcarriers are jointly optimized to
compensate for optical filtering impairments caused by cascaded reconfigurable optical add …

Relaxation oscillations are pervasive in diverse areas of natural sciences and engineering,
and exploring the dynamical mechanisms of relaxation oscillations is one of the most …
