We report on a mode locked semiconductor laser for high-power pulse generation in the 810-nm waveband. This is based on a novel GaAsP/GaInP single quantum-well structure, with Aluminum-free active region. Average output powers higher than 40 mW are r

We present a model for the description of the dynamical behavior of Quantum Dot (QD) based Semiconductor Optical Amplifiers (SOAs) under injection of optical pulses. The model uses a Time Domain Traveling Wave (TDTW) approach to describe the optical

Following pioneering work of Dicke [1] , the superradiance (SR) can be described by its quantum origin or semi-classically, the latter being widely used to interpret experimental results in high-gain optical media. Recent studies indicate that in a l

A wide spectral asymmetry between the wide and narrow facets of a two-section tapered quantum dot (QD) superluminescent diode (SLD) emitting around 1240 nm was observed and investigated. This asymmetry, as characterized by the mismatch in the center

We designed a guided-wave OPO integrated to a laser diode providing its pump field. This monolithic source, currently under fabrication, spans the spectrum between 1.8 and 2.4 µm, where tunable semiconductor lasers are hardly available.
