Abstract

This paper presents an optimal design of the waveguide separation and the orientation angle of the slabs for the arrayed waveguide gratings (AWGs) with low-crosstalk and low-loss. To demonstrate the effectiveness of the proposed method, a 16×16 AWG using silica-based sol-gel material is designed as an example to meet our prescribed specifications. The performance of the designed AWG is perfectly verified by simulation usingbeam propagation method (BPM). And the methodology of determining the optimal waveguide separation and the orientation angle of the slabs is simple and useful to obtain a low-crosstalk and low-loss AWG.
