Quantum-dot (QD) heterostructures are nanoscale coherent insertions of narrow-gap
material in a single-crystalline matrix. These tiny structures provide unique opportunities to …

The photoluminescence properties of I n A s/A ly Ga 1− y As self-assembled quantum dots
are studied as a function of temperature from 10 to 290 K. By varying the Al content the dot …

By measuring the spontaneous emission (SE) from normally operating/spl sim/1.3-/spl mu/m
GaInNAs-GaAs-based lasers we have quantitatively determined the variation of each of the …

A short historical review of the physics and technology of heterostructure lasers based on
double heterostructures is described. Recent progress in quantum dot laser structures and …

An InAs quantum dot (QD) array covered by a thin InGaAs layer was used as the active
region of diode lasers grown by molecular beam epitaxy on GaAs substrates. The …

The semiconductor laser, invented over 50 years ago, has had an enormous impact on the
digital technologies that now dominate so many applications in business, commerce and the …

The temperature dependence of quantum dot (QD) optical gain is analyzed using a
multilevel model and compared with experiment. The maximum gain is found to have a …
