摘要

对提高基于聚合物材料的WBG（波导布拉格光栅）的热光调制效率的方法进行了研究。根据聚合物材料的光学特性设计了三阶的WBG

仿真分析了WBG结构参数对光栅传输特性的影响;为提高热光调制效率

采用了内嵌式电极结构与在WBG两侧构建AT（空气沟槽）相结合的方案。模拟结果表明

与一般热光型调制结构相比

该方案的波长调谐灵敏度提升了1.87倍

实现了大范围的波长可调。所设计的热光可调WBG具有受热性强、热均匀性高及热串扰低等优点。

Abstract

In this paper

we investigate the method to improve the thermo-optic modulation efficiency of Waveguide Bragg Gratings（WBG）based on polymer material.According to the optical characteristics of polymer materials

a third-order WBG is designed.The effects of WBG structure parameters on the optical transmission spectrum of the WBG are also analyzed. In order to improve the thermooptic modulation efficiency

anembedded electrode structure combined with the Air Trenches（AT）symmetrically beside the WBG is proposed. The simulation results show that the wavelength-tuning sensitivity of the propose WBG structureis increased by 1. 87 times

which can achieve a broad wavelength-tuning range. Compared with general thermo-optic modulation structures

the designed thermooptically tunable WBG features strong heated ability

high heat uniformity and low thermal crosstalk.
