We review results on the optical injection of dual state InAs quantum dot-based
semiconductor lasers. The two states in question are the so-called ground state and first …

Semiconductor lasers are nowadays simply unavoidable and essential light sources. While
their complexity and dynamical behavior have attracted some attention from a fundamental …

Neurons communicate by brief bursts of spikes separated by silent phases and information
may be encoded into the burst duration or through the structure of the interspike intervals …

When theoretically investigating the nonlinear dynamics of quantum dot lasers (QDLs), the
parameter value of the electron escape rate (Ce) is sometimes approximated to zero to …

Simultaneous two‐state lasing is a unique property of semiconductor quantum‐dot (QD)
lasers. This not only changes steady‐state characteristics of the laser device but also its …

The optically injected semiconductor laser system has proven to be an excellent source of
experimental nonlinear dynamics, particularly regarding the generation of excitable pulses …

We demonstrate a tunable all-optical gating phenomenon in a single-section quantum dot
laser. The free-running operation of the device is emission from the excited state. Optical …

We numerically investigate the nonlinear dynamic properties of an exclusive excited-state
(ES) emission quantum dot (QD) laser under optical injection. The results show that, under …

One of the defining characteristics of excitability is the existence of an excitable threshold:
the minimum perturbation amplitude necessary to produce an excitable response. We …

Based on the cascade relaxation model of the quantum dot (QD) lasers, the nonlinear
dynamics of a two-state QD laser subject to optical injection is numerically studied. The …
