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 sio2 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.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-07-05t07:39:03z no. of bitstreams: 1 mode characteristics of metallically coated square microcavity connected with an output waveguide.pdf: 489759 bytes, checksum: 13e2ac86c0f048559e38a0403de7729e (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-07-05t07:47:03z (gmt) no. of bitstreams: 1 mode characteristics of metallically coated square microcavity connected with an output waveguide.pdf: 489759 bytes, checksum: 13e2ac86c0f048559e38a0403de7729e (md5); made available in dspace on 2010-07-05t07:47:03z (gmt). no. of bitstreams: 1 mode characteristics of metallically coated square microcavity connected with an output waveguide.pdf: 489759 bytes, checksum: 13e2ac86c0f048559e38a0403de7729e (md5) previous issue date: 2010; this work was supported by national nature science foundation of china under grant nos. 60777028, 60723002, and 60838003, and the major state basic research program under grant no. 2006cb302804.; 国内
