| 英文摘要 | mode radiation loss for microdisk resonators with pedestals is investigated by three-dimensional (3d) finite-difference time-domain (fdtd) technique. for the microdisk with a radius of 1 mu m, a thickness of 0.2 mu m, and a refractive index of 3.4, on a pedestal with a refractive index of 3.17, the mode quality (q) factor of the whispering-gallery mode (wgm) quasi-te7,1 first increases with the increase of the radius of the pedestal, and then quickly decreases as the radius is larger than 0.75 mu m. the mode radiation loss is mainly the vertical radiation loss induced by the mode coupling between the wgm and vertical radiation mode in the pedestal, instead of the scattering loss around the perimeter of the round pedestal. the wg m can keep the high q factor when the mode coupling is forbidden.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-06-05t07:12:49z no. of bitstreams: 1 investigation of mode radiation loss for microdisk resonators with pedestals by fdtd technique.pdf: 312898 bytes, checksum: ce321d4f2a137e4d45f8db2df4beaaa0 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-06-05t07:46:50z (gmt) no. of bitstreams: 1 investigation of mode radiation loss for microdisk resonators with pedestals by fdtd technique.pdf: 312898 bytes, checksum: ce321d4f2a137e4d45f8db2df4beaaa0 (md5); made available in dspace on 2010-06-05t07:46:50z (gmt). no. of bitstreams: 1 investigation of mode radiation loss for microdisk resonators with pedestals by fdtd technique.pdf: 312898 bytes, checksum: ce321d4f2a137e4d45f8db2df4beaaa0 (md5) previous issue date: 2010; this work was supported by the national natural science foundation of china (nos. 60777028, 60723002, and 60838003), the major state basic research program (no. 2006cb302804), and the project of national lab for tsinghua information technologies.; 其它 |
