Laser emission from a low number of InGaAs quantum dots embedded in optically and electrically pumped high-Q micropillar laser structures will be presented. The talk will focus on the demonstration of high-β low threshold lasing with threshold currents below 10µA and single quantum dot controlled gain modulation under optical excitation.

Abstract : This report describes the design, construction and characterization of a 2 dimensional micro laser array. The micro laser array consists of a monolithic pump array, microlenses, and a solid state gain module. Passive q-switching on a single element was also demonstrated on this program.

The idea of carrying a laser while jogging seems to suggest a particularly recherche refinement to what is already a masochistic activity. However, thanks to the portable compact disc player whose small size owes much to the miniature semiconductor diode laser at its heart, many joggers now happily add strains of a musical kind to their other strains ...

Membrane Microlasers and their Integration
Integrated Photonics and Nanophotonics Research and Applications, 2008We present various micro-nanophotonic devices based on the III-V on silicon heterogeneous integration scheme. We particularly focus on microdisk lasers integrated onto silicon wire waveguide, and on “2.5D” photonic crystal based surface emitting ...

Photonic crystals and microlasers
The 15th Annual Meeting of the IEEE Lasers and Electro-Optics Society, 2003Photonic nanostructure devices based on photonic crystals and high index contrast are now being studied worldwide for various applications. The miniaturization of devices and their high density integration are attractive targets. Some simple devices that provide novel high performance and/or unique characteristics are also expected.

The simplest and most fundamental system for studying radiation-matter coupling is a single two-level atom interacting with a single mode of an electromagnetic field in a cavity. It received a great deal of attention shortly after the maser was invented, but at that time, the problem was of purely academic interest since the matrix elements describing ...
