介绍了一种新型16通道、100GHz通道间隔的硅基二氧化硅单侧耦合阵列波导光栅(AWG).通过增加一个Y分支波导结构,并且将AWG的输入、输出波导等间距整齐排列,实现了仅用一个光纤阵列进行AWG器件的耦合封装.这种AWG的结构设计可以有效地减小器件尺寸,增加波导结构的弯曲半径,减少器件抛光及耦合时间,并降低器件成本.

A novel design of 100GHz-spaced 16channel arrayed-waveguide grating (AWG) based on silica-on-silicon chip is reported.AWG is achieved by adding a Y-branch to the AWG and arranging the input/output channel in a neat row,so the whole configuration can be aligned and packaged using only one fiber-array.This configuration can decrease the device's size,enlarge the minimum radius of curvature,save time on polishing and alignment,and reduce the chip's fabrication cost.
