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.

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.
