Lightwave communications is a necessity for the information age. Optical links provide
enormous bandwidth, and the optical fiber is the only medium that can meet the modern …

We review the most recent progress in ultralow-noise mode-locked fiber lasers and fiber-
based frequency-comb sources. With the rapid progress in theory, measurement, and …

Microwave photonic technologies, which upshift the carrier into the optical domain, have
facilitated the generation and processing of ultra-wideband electronic signals at vastly …

Solitons are waveforms that preserve their shape while propagating, as a result of a balance
of dispersion and nonlinearity,. Soliton-based data transmission schemes were investigated …

The ability to amplify optical signals is of pivotal importance across science and technology
typically using rare-earth-doped fibres or gain media based on III–V semiconductors. A …

Recently, integrated photonics has attracted considerable interest owing to its wide
application in optical communication and quantum technologies. Among the numerous …

Dissipative Kerr soliton microcombs have been recognized as a promising multi-wavelength
laser source for fiber optical communications, as their comb lines possess frequency and …

Microresonator frequency combs harness the nonlinear Kerr effect in an integrated optical
cavity to generate a multitude of phase-locked frequency lines. The line spacing can reach …

One of the main reasons why nonlinear-optical signal processing (regeneration, logic, etc.)
has not yet become a practical alternative to electronic processing is that the all-optical …

This paper reviews optical injection locking (OIL) of semiconductor lasers and its application
in optical communications and signal processing. Despite complex OIL dynamics, we …
