中文摘要	mode characteristics of three-dimensional (3-d) microsquare resonators are investigated by finite-difference time-domain (fdtd) simulation for the transverse electric (te)-like and the transverse magnetic (tm)-like modes. for a pillar microsquare with a side length of 2 pin in air, we have q-factors about 5 x. 103 for tm-like modes at the wavelength of 1550 run, which are one order larger than those of te-like modes, as vertical refractive index distribution is 3.17/3.4/3.17 and the cororresponding center layer thickness is 0.2 mu m. the mode field patterns show that tm-like modes have much weaker vertical radiation coupling loss than te-like modes. tm-like modes can have high q-factors in a microsquare with weak vertical field confinement.
