### Abstract

The mode characteristics of a three-dimensional (3D) microdisk with a vertical refractive index distribution of *S*-matrix method and 3D finite-difference time-domain (FDTD) technique. For the microdisk with a thickness of *S*-matrix method are in good agreement as *Q* factor obtained by the 3D FDTD rapidly decreases from *S*-matrix method. The comparisons also show that quality factors obtained from the analytical solution of two-dimensional microdisks under the effective index approximation are five to seven times smaller than those of the 3D FDTD as
