microdisk laser

microdisk laser

[′mī·krō‚disk ‚lā·zər]
(optics)
A very small semiconductor laser that consists of a quantum well structure formed into a disk, such that total internal reflection of photons traveling around the perimeter of the disk results in high-Q whispering-gallery resonances.

He has made important accomplishments in such diverse areas as light scattering from semiconductors and liquid helium, laser diagnostics of tokomak plasmas for fusion studies, squeezed state generation and the application of squeezed states to sensitive measurement, whispering-gallery mode microdisk lasers, and optical pulse propagation in nonlinear media.
These microdisk lasers operate in what researchers call a "whispering gallery" mode, named for the way words whispered at one location near the interior wall of a circular, domed chamber can be readily overheard anywhere else along the wall.
Deformed wavelength-scale microdisk lasers with quantum dot emitters.
Once the microdisk lasers are formed, the lasers' substrate (the indium phosphide [InP] platform on which the indium gallium arsenide phosphide [InGaAsP] lasers were built) is etched away.
These small, fast, low-power microdisk lasers are part of our research effort," said Richard Slusher, head of Bell Labs Optical Physics Research department.
