Quantum-dot (QD) lasers exhibit many useful properties such as low threshold current,
temperature and feedback insensitivity, chirpless behavior, and low linewidth enhancement …

The dynamic properties of distributed feedback lasers (DFBs) based on InAs/InGaAs
quantum dots (QDs) are studied. The response function of QD DFBs under external …

We measure, for the first time, the gain compression coefficient and above-threshold
linewidth enhancement factor (alpha parameter) in quantum dot (QD) distributed feedback …

Optical characterization at the nanoscale currently requires instruments such as
NSOM/TERS, or hybrid AFM with specialized far-field optical microscopes that are quite …

Self-organized growth mechanisms have been intensively investigated for the last decade
as a powerful way to achieve a variety of high quality quantum confined structures. Among …

Actoprobe LLC reports on the results of its DOE SBIR Phase II/IIA project on the
development of Atomic Force Microscope Active Optical Probe for Single-Molecule Imaging …

Semiconductor quantum dots (QDs) are nano-structures with three-dimensional spatial
confinement of electrons and holes, representing the ultimate case of the application of the …

This work investigates the linewidth enhancement factor (alpha-factor) and stability of an
optically-injected InAs/InGaAs quantum-dot Fabry-Perot laser. Using the injection-locking …
