Abstract
Semiconductor optical microresonators are of interest for studies of quantum electrodynamic modifications of spontaneous emission and for low-threshold microlasers and light-emitting diodes. As the optical-mode volume of a microresonator approaches a cub wavelength in the semiconductor, the number of modes interacting with the optically active spectral region in the microresonator approaches unity. High-Q optical microresonators with strong optical confinement to quantum-well gain regions can be obtained by using the whispering-gallery modes around the edge of a semiconductor disk.
