Abstract :
The mode characteristics of a microcylinders with center layer thickness 0.2 mum and radius 1 mum are investigated by the three-dimensional (3D) finite-difference time-domain (FDTD) technique and the Pade approximation. The mode quality factor (Q-factor) of the EH71 mode obtained by 3D FDTD increase with the increase of the refractive index of the cladding layer n2 as n2 smaller than 3.17, and can be as large as 2.4 times 104 as the vertical refractive index distribution is 3.17/3.4/3.17, which is much larger than that of the HE71 mode with the same vertical refractive index distribution.
