Excitation of forced modes in the dielectric disk resonator-diffraction grating system [PDF]
Журнал нано- та електронної фізики, 2010 In this work the strip-like diffraction grating influence on the spectrum of “whispering gallery” modes of the disk dielectric resonator was studied experimentally. The conditions of single-mode excitation in a wide frequency range had been defined.

Tunable Whispering Gallery Mode Resonators for Cavity Quantum Electrodynamics
, 2005 We theoretically study the properties of highly prolate shaped dielectric microresonators. Such resonators sustain whispering gallery modes that exhibit two spatially well separated regions with enhanced field strength.
