We report a dual-wavelength passive mode locking regime where picosecond pulses are
generated from both ground (λ= 1263nm) and excited state transitions (λ= 1180nm), in a …

Quantum-dot lasers can exhibit simultaneous ground-and excited-state lasing. With
increasing pump current, a quenching of the ground-state lasing intensity is sometimes …

We analyze an electron-hole asymmetry model for simultaneous two-state operation in
semiconductor quantum dot lasers. From the linearized equations, we determine simple …

André Röhm investigates the dynamic properties of two-state lasing quantum dot lasers, with
a focus on ground state quenching. With a novel semi-analytical approach, different …

The influence of different biasing conditions of a passively mode-locked strongly chirped two-
section quantum-dot laser on its ground state (GS) and excited state (ES) emission is …

Self-sustained pulsations in the output of an InAs quantum dot laser diode in the MHz range
are reported. The characteristics (shape, range, and frequency) are presented for the free …

We present a modified version of the multisection delayed differential equation model, for
quantum dot passively mode-locked (ML) lasers when competition between ground state …

Reverse-emission-state-transition mode locking in a two-section InAs/InGaAs quantum dot
laser is experimentally investigated and confirmed by simulations. Stable mode locking …

We experimentally and numerically study the amplitude stability of an InAs/InGaAs quantum
dot laser emitting simultaneously on ground states (GSs) and excited state (ESs) at center …

In this work, we present experimental results concerning excitability in a multiband emitting
quantum-dot-based photonic neuron. The experimental investigation revealed that the same …
