Complex phenomena in photonics, in particular, dynamical properties of semiconductor
lasers due to delayed coupling, are reviewed. Although considered a nuisance for a long …

Pattern formation and competition occur in a nonlinear extended medium if dissipation
allows for attracting sets, independently of initial and boundary conditions. This intrinsic …

In this chapter, we discuss the oscillation conditions for semiconductor lasers and, then,
derive the rate equations, which are the starting points of the study of chaotic dynamics in …

Terahertz (THz) frequency quantum cascade lasers emitting peak powers of> 1 W from a
single facet in the pulsed mode are demonstrated. The active region is based on a bound‐to …

In this review we discuss the theoretical framework needed for studying the dynamical
behaviour of semiconductor lasers exposed to three kinds of optical modulation. We start by …

As recognized almost immediately following the design of the first laser [1, 2], lasers are
dynamical systems capable of exhibiting a wide variety of nonlinear dynamics. For many …

There are three nonlinear mechanisms that can lead to filamentation in broad-area
semiconductor lasers: gain-saturation-induced changes in the refractive index through the …

Abstract Space-dependent Maxwell-Bloch equations are derived for the description of
spatiotemporal dynamics of spatially inhomogeneous semiconductor lasers. The dynamics …

A set of effective Bloch equations is established for semiconductor bulk or quantum-well
media. The model includes the nonlinear carrier-density dependence of the gain and …

We present the combination of microscopic model calculations and direct experimental
evidence for complex spatio-temporal dynamics on a picosecond timescale in the near-field …
