Non-binary low-density parity-check (NB-LDPC) codes show higher error-correcting
performance than binary low-density parity-check (LDPC) codes when the codeword length …

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

The modulator is a key component in optical communications. Several graphene-based
amplitude modulators have been reported based on electro-absorption. However, graphene …

Industry 4.0 aims to digitize industrial processes entirely, and wireless technologies
represent one of the enablers for scalable and flexible communications. However, the …

Future-proofing current fibre networks with quantum key distribution (QKD) is an attractive
approach to combat the ever growing breaches of data theft. To succeed, this approach must …

Abstract Machine learning techniques have proven very efficient in assorted classification
tasks. Nevertheless, processing time-dependent high-speed signals can turn into an …

While many communications media, such as wireless and certain classes of wireline
channels, typically lead to bursty errors, most decoders are designed assuming memoryless …

Free-space optical communication holds the promise of high-throughput wireless
communication channels for long distances as well as for short-range indoor applications …

In this paper, we experimentally demonstrate the benefit of polarization insensitive dual-
band optical phase conjugation for up to ten 400 Gb/s optical super-channels using a …

This tutorial discusses the design and ASIC implementation of coherent optical transceivers.
Algorithmic and architectural options and tradeoffs between performance and …
