| 英文摘要 | Mode characteristics of a square microcavity with an output waveguide on the middle of one side, laterally confined by an insulating layer sio(2) and a p-electrode metal au, are investigated by two-dimensional finite-difference time-domain technique. the mode quality (q) factors versus the width of the output waveguide are calculated for fabry-peacuterot type and whispering-gallery type modes in the square cavity. mode coupling between the confined modes in the square cavity and the guided modes in the output waveguide determines the mode q factors, which is greatly influenced by the symmetry behaviors of the modes. fabry-peacuterot type modes can also have high q factors due to the high reflectivity of the au layer for the vertical incident mode light rays. for the square cavity with side length 4 mu m and refractive index 3.2, the mode q factors of the fabry-peacuterot type modes can reach 10(4) at the mode wavelength of 1.5 mu m as the output waveguide width is 0.4 mu m.
