Selective 1.3 μm Laser Emission via Coupled Microlaser for Laser Resonance Tuning
ACS PhotonicsA 1.3 μm laser has significant application value in the fields of optical communication and spectral analysis. However, existing optically pumped Whispering-Gallery Microcavity (WGM) are unable to achieve excitation of the 1.3 μm laser due to the ...

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 ...

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.

An Ultralow-Threshold Microlaser
EQEC 96 1996 European Quantum Electronic Conference EQEC-96, 1996In our experiment Nd3+ ions are pumped with a diode laser at 807nm using a resonant WG mode. The coupling to this mode is achieved via frustrated total internal reflection using a high index prism. The emission from the ions is then coupled out via the Same prism and is diagnosed using a spectrometer and a Fabry-Perot.

Journal of Modern Optics, 1997
Abstract The cooperative dynamics of a microlaser consisting of two threelevel atoms interacting with a pump field and two quantized cavity modes forming a radiative cascade are studied. Adiabatic elimination of one mode leads to a strong dynamical entanglement between the internal states of the atoms which allows us to study the effects of a cavity ...

Asia Communications and Photonics Conference and Exhibition, 2009
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.

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 ...

Quantum theory of the microlaser
OSA Annual Meeting, 1993The phase-transition analogy of the thresholdless microlaser will be fully analyzed by including the fluctuation contributions of the atomic reservoir and of the emitted field.1 ...
