| 英文摘要 | Mode characteristics of a strongly confined square cavity suspended in air via a pedestal on the substrate are investigated by a three-dimensional finite-difference time-domain technique. the mode wavelengths and mode quality factors (q factors) are calculated as the functions of the size of the pedestal and the slope angle 0 of the sidewalls of the square slab, respectively for the square slab with side length of 2 mu m, thickness of 0.2 mu m, and refractive index of 3.4, on a square pedestal with refractive index of 3.17, the q factor of the whispering-gallery (wg)-like mode transverse-electric te(3.5)o first increases with the side length b of the square pedestal and then quickly decreases as b > 0.4 mu m, but the q factor of the wg-like mode te(4.6)o drops down quickly as b > 0.2 mu m, owing to their different symmetries. the results indicate that the pedestal can also result in mode selection in the wg-like modes. in addition, the numerical results show that the q factors decrease 50% as the slope angle of the sidewalls varies from 90 degrees to 80 degrees. the mode characteristics of wg-like modes in the square cavity with a rectangular pedestal are also discussed. the results show that the nonsquare pedestal largely degrades the wg-like modes.
