The advances in lasers, electronic and photonic integrated circuits (EPIC), optical
interconnects as well as the modulation techniques allow the present day society to …

We present a spatially resolved model for multilayer quantum-dot (QD) lasers. The detailed
model incorporates the homogeneous and inhomogeneous gain broadenings. Using this …

We report on a characterization of fundamental gain dynamics in recently developed
InAs/InP quantum-dot semiconductor optical amplifiers. Multi-wavelength pump-probe …

The charge carrier dynamics of improved InP-based InAs/AlGaInAs quantum dot (QD)
semiconductor optical amplifiers are examined employing the multi-wavelength ultrafast …

We demonstrate a novel laser oscillation scheme in an InAs/InP wire-like quantum dash
gain medium. A short optical pulse excites carriers by two photon absorption which relax to …

We describe direct measurements at a high temporal resolution of the changes experienced
by the phase and amplitude of an ultra-short pulse upon propagation through an …

In this work, we investigate the importance of lateral electronic coupling in a dense
ensemble of anisotropic epitaxial nanostructures called quantum dashes. The respective …

The ultrafast carrier dynamics in a p-doped dash-in-a-well structure at 1.5 μm is
experimentally investigated. An analysis of the timescales related to carrier relaxation and …

We report on a unique lasing mechanism observed in quantum dash Gain media. While the
gain media is electrically pumped below lasing threshold, a strong optical pulse excites …

Today, when one can access Internet through device of a size of woman's palm the next step
is to make this telecommunication fast and accurate, to send a lot of data without any …
