Simulation Results

In this paper, the boundary rounding effects of two types of non-circular GaN microcavity system are numerically simulated by the finite element method. When the rounding parameter [Formula: see text] of the hexagonal microcavity decreases, the six corners of the regular hexagon are gradually rounded, the results show that the optical mode gradually changes from the hexagonal whispering-gallery mode (WGM) to the perfect circular WGM, and the quality factor of the modes increases correspondingly. For the oval microcavity, the structure parameter [Formula: see text] increases from 0 to 1 when the oval microcavity gradually changes from a stadium cavity to a circular cavity. The simulation results show that the quality factor increases with [Formula: see text], and the optical mode changes from high-leak mode to WGM. Our results demonstrate the effect of the boundary rounding on the mode pattern and quality factor in hexagonal and oval microcavities.

Em Field

In the past decade, optical microcavity whispering-gallery mode (WGM) resonators have received increasing attention for applications in optical communications and nanotechnology. In this paper, the theory for describing radiation transfer and heat transfer in the micro/nanoscale devices is presented first. Then the characteristics of waveguide-microdisk coupling WGM miniature resonators are numerically studied. Focus is placed on the parametric studies over a broad range of resonator configuration parameters including the microcavity size and the gap separating the microdisk and waveguide. The finite element method is used for solving Maxwell’s equations which govern the propagation of electromagnetic field and the radiation energy transport in the micro/nanoscale devices. The EM field and the radiation energy distributions are obtained and compared between the on-resonance and off-resonance cases. A very brilliant ring with strong EM field and high radiation intensity is found inward the periphery of the microdisk under resonances and high energy storage is achieved. The microdisk size affects significantly the resonant frequencies and their intervals. The scattering spectra for three different microcavity sizes are obtained. The gap obviously influences the qualify factor, the full width at half maximum, and the finesse of the resonant modes as well as the capability of energy storage.
