Polymeric flat focal field arrayed waveguide grating using electron-beam direct wiring

A four-channel 400 GHz spacing flat focal field arrayed waveguide grating (AWG) demultiplexer is designed based on polymerie optical waveguide. The waveguide core-layer material is a newly developed negative tone epoxy Novolak resin (ENR) polymer with ultravoilel (UV) cured resin Norland optical adhesive 61 (NOA61) as the clodding layer. The device is fabricated using electron-beam direct writing, which has less professing steps than the reported polymeric AWGs. The experimental result is presented.     

低偏振相关损耗聚合物光波导

表征了新合成的热光聚合物bisphenol A-aldehyde resin (BPA-resin)的独特性质。并且利用光刻和反应离子刻蚀技术(RIE)制备成功BPA-resin 聚合物的单模条波导.实验结果表明,对于TE和TM偏振,该聚合物波导在1.31 μm和1.55 μm波长下分别有低达0.43 dB/cm和0.51 dB/cm的传播损耗.在上述波长下,波导的低偏振相关损耗 (PDL)小于0.1 dB/cm.因此,是制备可调热光器件的良好导波模快.
