Abstract

The parameters of coupling system composed by microtoroid cavity and fiber-taper such as coupling distance, the size of the microtoroid cavities and the wavelength of the input light directly affect its coupling property. It has been fabricated in our laboratory and Rsoft Fullwave based on FDTD is used to simulate different size of micro-cavities, coupling distance from 0.1 mum to 0.5 mum, and the wavelength of input light around 0.85 mum, 1.31 mum and 1.55 mum corresponding to individual optical-windows of optical fiber. It shows that the relationship among parameters mentioned can get an analysis through evanescent wave theory.
