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 …

The Kerr nonlinearity can be a key enabler for many digital photonic circuits as it allows
access to bistable states needed for all-optical memories and switches. A common …

We have demonstrated an all-optical memory by using InGaAsP/InP buried heterostructure
photonic crystal (BH-PhC) lasers. We achieved distinct optical injection locking bistability in …

We show that the long-established concept of a linewidth-enhancement factor α to describe
carrier-induced refractive index changes in semiconductor lasers breaks down in quantum …

Lasers designed to emit at multiple and controllable modes, or multi-wavelength lasers,
have the potential to become key building blocks for future microwave photonic …

Polarization switching in a long-wavelength vertical-cavity surface-emitting laser (VCSEL)
under parallel optical injection is analyzed in a theoretical and experimental way. For the …

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

We investigate theoretically the impact of optical feedback on quantum dot two-color laser
dynamics when emitting from both the excited and the ground states. Detailed analysis of …

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 …
