Abstract

For the first time, a new-type flat focal field arrayed waveguide grating (AWG) demultiplexer, with the focal signals of all wavelengths of operation focusing along a straight line, is designed based on the aberration theory and fabricated based on a newly developed negative tone epoxy Novolak resin (ENR) polymer using electron-beam direct writing. A polymeric four-channel 400GHz spacing flat focal field AWG demultiplexer is fabricated and tested. Four modal images from the output waveguides are observed and the measured transmission spectra is presented. And we make error analysis.

摘要

首次基于像差理论设计了一种新型平面聚焦场阵列波导光栅（AWG）解复用器，其工作的所有波长的聚焦信号沿直线聚焦，并基于新开发的负性环氧酚醛清漆树脂（ENR）聚合物，采用电子束直写技术进行制造。制作并测试了一个聚合物四通道、间距为400GHz的平面聚焦场AWG解复用器。观察了来自输出波导的四个模式图像，并给出了测量的传输光谱。并且我们进行了误差分析。
