Title: Low-order optical whispering-gallery modes in hexagonal nanocavities

Abstract

We present a detailed numerical analysis of the lowest-order resonant modes of a hexagonal dielectric cavity. Our investigations include resonant wave numbers, linewidths, mode patterns, and their dependency on the refractive index. On the basis of our theoretical results, we are able to simulate the resonance spectra of individual hexagonal zinc oxide nanocavities without a free parameter. A superposition of Lorenzian resonance lines leads to perfect agreement with experimental data obtained from polarization-resolved micro-photoluminescence and cathodoluminescence spectroscopy. Series of radially higher-order modes are theoretically predicted and experimentally observed. Therefore, we present a consistent description of the resonance behavior of a hexagonal dielectric optical cavity on nanoscopic scale.

  • We report picosecond time-resolved measurements of optical pulse propagation in dielectric spheres (8, 10, and 26thinspthinspmm in diameter) for which the pulse duration ({approx}2 ps) was short compared with the equatorial round-trip time within the sphere. A size-independent buildup of the leakage intensity in terms of the number of round trips was observed for each of the spheres, as were damped low-frequency oscillations superimposed upon the pulse ringdown envelope. These features of the data are interpreted as resulting from perturbative coupling of eigenmodes of the sphere and trajectory precession near the observation region. {copyright} {ital 1998} {ital Optical Society ofmore » America}« less
  • A change in the spectrum of optical whispering-gallery modes in a quasi-cylindrical microresonator caused by an acoustic pressure pulse produced by a laser pulse, which was predicted earlier, was observed experimentally for the first time. (letters)
  • It is a well-known fact that a single nanoparticle placed in the evanescent field of an optical microdisk leads to coherent backscattering of light between counterpropagating whispering-gallery modes. This backscattering lifts the spectral degeneracy giving rise to a doublet of standing-wave modes. Here, we show that the evanescent coupling of two or more nanoparticles leads in general to asymmetric backscattering (i.e., the strength of the scattering of light from the clockwise to the counterclockwise propagation direction is different than the other way around). Even if the strength of the backscattering is weak its asymmetry can have a dramatic impact onmore » the mode structure. In the regime of overlapping resonances the modes do not have a standing-wave character. Instead nonorthogonal pairs of mainly copropagating modes are formed. In the extreme case the pair of optical modes coalesce at a so-called exceptional point. We derive an effective Hamiltonian within a two-mode approximation which reveals that this unexpected behavior is due to interference of the scattered waves which can be destructive or constructive depending on the propagation direction of the light.« less
