A full-vectorial boundary integral equation method is presented for calculating the resonant spectra of arbitrary shape 2-D dielectric cavities together with near-field and far-field patterns and Q-factors. Very fast, stable and robust algorithms developed based on the method enable us to simulate and optimize the performance of WG-mode optical microcavities widely used in dense WDM systems. The. effect on the cavity characteristics of introducing special deformations and/or evanescent coupling to bus waveguides is analyzed. Frequency tuning and Q-factor control is demonstrated.
