A boundary element method based on a Green function technique is introduced to compute resonances with intermediate lifetimes in quasi-two-dimensional dielectric cavities. It can be applied to single or several optical resonators of arbitrary shape, including corners, for both TM and TE polarization. For cavities with symmetries a symmetry reduction is described. The existence of spurious solutions is discussed. The efficiency of the method is demonstrated by calculating resonances in two…

Quick root searching method for resonances of dielectric optical microcavities with the boundary element method.

An efficient method for searching the resonant eigenfrequency of dielectric optical microcavities by the boundary element method, which can predict multiple resonances, increase the speed of convergence, and avoid non-physical spurious solutions is developed.

The optical resonance problem is similar to but different from time-steady Schrodinger equation. One big challenge is that the eigenfunctions in resonance problem is exponentially growing. We give

Ray and wave chaos in asymmetric resonant optical cavities

OPTICAL resonators are essential components of lasers and other optical devices. A resonator is characterized by a set of modes, each with a resonant frequency ω and resonance width δω= 1/τ, where τ
