Rayleigh scattering of whispering gallery modes of microspheres due to a single dipole scatterer
نویسندگان
چکیده
An exact solution for the problem of interaction between whispering gallery modes of spherical microresonators and a single dipole is presented. It is predicted that experimentally observed spectral doublets associated with this interaction are a part of a triplet whose third component has yet to be observed. It is also shown that the interaction between the dipole and nonresonant whispering gallery modes results in a renormalization of the dipole’s polarizability and experimental manifestations of this effect are discussed.

Surface optomechanics: calculating optically excited acoustical whispering gallery modes in microspheres.
Stimulated Brillouin scattering recently allowed experimental excitation of surface acoustic resonances in micro-devices, enabling vibration at rates in the range of 50 MHz to 12 GHz. The experimental availability of such mechanical whispering gallery modes in photonic-MEMS raises questions on their structure and spectral distribution. Here we calculate the form and frequency of such vibrationa...
متن کاملControlled coupling of counterpropagating whispering-gallery modes by a single Rayleigh scatterer: a classical problem in a quantum optical light.
We present experiments where a single subwavelength scatterer is used to examine and control the backscattering induced coupling between counterpropagating high-Q modes of a microsphere resonator. Our measurements reveal the standing wave character of the resulting symmetric and antisymmetric eigenmodes, their unbalanced intensity distributions, and the coherent nature of their coupling. We dis...
متن کاملAb initio theory of defect scattering in spherical whispering-gallery-mode resonators
An exact formalism for the interaction of a spherical whispering-gallery-mode (WGM) microresonator with an externally or internally placed subwavelength scatterer is developed. The experimentally observed doublets in the spectra of high-Q microspheres are shown to correspond to the ideal Mie resonance and a defect-induced resonance, while for TM-polarized WGMs a third peak is predicted. Explici...
متن کاملAtom galleries for whispering atoms: binding atoms in stable orbits around an optical resonator.
The external fields of optical whispering gallery modes may be used to confine atoms in stable orbits around a dielectric microsphere. As an example, a toroidal dipole-force trap (atom gallery) for three-level atoms is investigated, and the possibility of achieving an atomic (matter-wave) resonator is discussed. The extremely small electromagnetic mode volumes and high Q's of the whispering gal...
