In real-world dynamical systems, technical limitations may prevent complete access to their
dynamical variables. Such a lack of information may cause significant problems, especially …

We employ a nonequilibrium energy balance and carrier rate equation model based on
microscopic semiconductor theory to describe the quantum-dot (QD) laser dynamics under …

Quantum dot lasers display many unique dynamic phenomena when optically injected.
Bistability has been predicted in a region of high injection strength. Experimentally, we show …

This thesis sheds light on the unique dynamics of optoelectronic devices based on
semiconductor quantum-dots. The complex scattering processes involved in filling the …

It has been experimentally and theoretically analyzed that noise-induced excitability in
quantum well and quantum dot semiconductor laser systems usually produces sharp spike …

Quantum dot lasers can lase from the ground state only, simultaneously from both the
ground and first excited states and from the excited state only. We examine the influence of …

Neuromorphic computing has garnered a lot of attention in recent years. Excitable photonic
systems in particular demonstrate great potential for ultrafast, controllable spike processing …

Two routes to phase-locking in the optically injected laser system are investigated both
involving limit cycles where the phase of the slave laser is unlocked but is nevertheless …

The dynamical properties of an optical neuron formed by a quantum dot semiconductor laser
model subjected to optical injection and optical feedback are analyzed. The parameter …

Optically injected quantum dot lasers display many unique nonlinear phenomena and are in
particular, excellent testbeds for different forms of excitability. We analyse the recent …
