Abstract

In this presentation, first we investigate the diffusion process analytically and numerically. Some important fabrication and design parameters are abstracted and used for the next level simulation. Then we applied the efficient method to analyze the modal properties of the diffused waveguides. The accuracy and the scope of validity for the analytical methods are investigated and the modal properties directly link to the fabrication parameters. Based on modal properties of optimized waveguides, the device performances of the related devices can be easily obtained. The relation between the waveguide modal performance and design parameters is built and the possible optimization methods can be applied. Finally, some related issues such as the bending loss and the coupling loss with the standard fiber are discussed.
