Abstract Ultra-small, low-power, all-optical switching and memory elements, such as all-
optical flip-flops, as well as photonic integrated circuits of many such elements, are in great …

In the near future, technological advances driven by the Fourth Industrial Revolution will
boost the demand for integrated, power-efficient miniature lasers, which are important for …

Synchronisation of two unidirectionally coupled semiconductor ring lasers working in a
chaotic regime (transmitter and receiver) is studied numerically. Two different configurations …

We present experimental results on the emission characteristics of a 1.5-μm distributed
feedback (DFB) tapered master oscillator power amplifier (MOPA) in a wide range of steady …

We show that a topological investigation of the phase space of a semiconductor ring laser

We theoretically discuss the impact of the cavity configuration on the possible longitudinal
mode multistability in homogeneously broadened lasers. Our analysis is based on the most …

We investigate numerically the dynamical behavior in a semiconductor ring laser (SRL)
subject to a periodic modulation of the injection current. By varying the amplitude and …

The multimode dynamics of a two-level ring laser is explored numerically using a
bidirectional traveling wave model retaining the spatial effects due to the presence of …

All-optical directional switching of bistable semiconductor ring lasers is studied by numerical
simulations of a traveling-wave model. We discuss how the reversal depends on the bias …

A general and comprehensive frequency-domain model of longitudinal mode interactions in
semiconductor ring lasers (SRLs) is presented, including nonlinear terms related to third …
