Graded-index whispering gallery mode resonators [PDF]

open access: yes, 2005
Whispering gallery mode optical resonators which have spatially-graded refractive indices. In one implementation, the refractive index spatially increases with a distance from an exterior surface of such a resonator towards an interior of the resonator ...

Observation of whispering gallery modes in the mid-infrared with a quantum cascade laser: possible applications to nanoliter chemical sensing [PDF]

open access: yes, 2009
Excitation of the whispering gallery modes (WGM) of a CaF_2 ball resonator is demonstrated at 4.5 micron with a pulsed Quantum Cascade laser. A prism coupling scheme for mid-infrared is described.

Whispering gallery germanium-on-silicon photodetector

open access: yesOptics Letters, 2017
We design and demonstrate, to the best of our knowledge, the first whispering gallery germanium-on-silicon photodetector with evanescent coupling from a silicon bus waveguide in a CMOS-compatible process. The small footprint (63.6  μm2), high responsivity (∼1.04  A/W at 1530 nm), low bias voltage (-1  V), low dark current (2.03 nA), and large ...

Excitation of forced modes in the dielectric disk resonator-diffraction grating system [PDF]

open access: yesЖурнал 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.

Whispering gallery modes in open quantum billiards

open access: yes, 2001
The poles of the S-matrix and the wave functions of open 2D quantum billiards with convex boundary of different shape are calculated by the method of complex scaling. Two leads are attached to the cavities.
