Morphology-Dependent Resonances

History of Optical Trapping and Manipulation of Small Neutral Particles, Atoms, and Molecules

“…High-Q resonances yield 2-3 orders of magnitude improvement in absolute and relative size and index of refraction measurement of spheres [11,13]. More recently, drops have served as extremely high-Q dye laser and Raman laser resonators and as a medium for studying and enhancing a wide range of linear and nonlinear optical interactions [14]. Mirrorless optical resonators based on these modes have the highest Q's of any optical cavity (> 2 x 10 9 ) [15] and have recently been used for low threshold semiconductor lasers [16,17] and for experiments in cavity electrodynamics [18].…”

“…In Bose-Einstein condensates in the vapor phase, the likelihood of three-body collisions, which might result in the formation of molecules or atomic clusters, is much reduced. In this sense the vapor condensate is metastable for times 14 A. Ashkin of seconds or minutes. However, once formed, the atomic vapor condensate is the purest macroscopic quantum system yet achieved.…”

Computation of Nonlinear Optical Scattering by Droplets.

“…The effects typically occur in droplets with lower intensities than are required in bulk materials. The primary reason for the lower thresholds is the optical feedback provided by morphology dependent resonances, MDR's [12][13]. If the refractive index of the droplet is a function of both time and space, because of its dependence on the internal intensity, the MDR's and quality factors, Q's, are also time varying.…”

Reconfigurable optical spectra from perturbations on elliptical whispering gallery resonances

“…These demonstrations have all been made with resonators having fixed spectra. The mode frequencies of the WGMs are determined by the resonator radius and the refractive index of the host material [3,4]. In spherically symmetric boundaries, the spectrum is highly degenerate, but any modification of the resonator morphology can break this degeneracy.…”
