英文摘要	coupled microcircular resonators tangentially coupled to a bus waveguide, which is between the resonators, are numerically investigated by the finite-difference time-domain technique. for symmetrically coupled microcircular resonators with refractive index of 3.2, radius of 2 mu m, and width of the bus waveguide of 0.4 mu m, a mode q factor of the order of 105 is obtained for a mode at the frequency of 243 thz. an output coupling efficiency of as high as 0.99 is calculated for a mode with a q factor ranging from 10(3) to 10(4). the mode q factor is 2 orders larger than that of the modes confined in a single circular resonator tangentially coupled to the same bus waveguide. furthermore, the high q traveling modes in the coupled microcircular resonators are suitable for optical single processing.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-07-18t13:51:41z no. of bitstreams: 1 analysis of coupled microcircular resonators coupled to a bus waveguide with high output efficiency.pdf: 342790 bytes, checksum: 068d9c7979b75aae0a41c5f3e1bfa76d (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-07-18t13:56:06z (gmt) no. of bitstreams: 1 analysis of coupled microcircular resonators coupled to a bus waveguide with high output efficiency.pdf: 342790 bytes, checksum: 068d9c7979b75aae0a41c5f3e1bfa76d (md5); made available in dspace on 2010-07-18t13:56:06z (gmt). no. of bitstreams: 1 analysis of coupled microcircular resonators coupled to a bus waveguide with high output efficiency.pdf: 342790 bytes, checksum: 068d9c7979b75aae0a41c5f3e1bfa76d (md5) previous issue date: 2010; we gratefully acknowledge the financial support from the national natural science foundation of china (nsfc) under grants 60777028, 60723002, and 60838003, the major state basic research program under grant 2006cb302804, and the project of national lab for tsinghua information technologies.; 其它
