选择在可见光波段具有较低吸收损耗的聚甲基丙烯酸甲酯-甲基丙烯酸环氧丙酯[P(MMA-GMA)]共聚物作为波导包层材料,使用双酚A型环氧树脂作为折射率调节剂,根据材料的折射率设计了单模波导截面尺寸;然后,采用束传播法优化设计出16信道阵列波导光栅(AWG)器件的版图结构。利用Optiwave软件模拟了AWG器件的光传输特性,结果显示,器件的信道间隔为0.845 01 nm,插入损耗小于14 dB,串扰小于-25 dB。
選擇在可見光波段具有較低吸收損耗的聚甲基丙烯痠甲酯-甲基丙烯痠環氧丙酯[P(MMA-GMA)]共聚物作為波導包層材料,使用雙酚A型環氧樹脂作為摺射率調節劑,根據材料的摺射率設計瞭單模波導截麵呎吋;然後,採用束傳播法優化設計齣16信道陣列波導光柵(AWG)器件的版圖結構。利用Optiwave軟件模擬瞭AWG器件的光傳輸特性,結果顯示,器件的信道間隔為0.845 01 nm,插入損耗小于14 dB,串擾小于-25 dB。

By choosing Polymethyl Methacrylate-glycidyl Methacrylate[P(MMA-GMA)] with a low absorption loss at 650 nm as the cladding material of a waveguide,and taking the bisphenol A epoxy resin as the refractive index modifier,the cross section size of a single mode waveguide was designed according to the refractive index of the cladding and core material.Then the layout of a 16-channel Arrayed Waveguide Grating(AWG) was designed and optimized using beam propagation method.The Optiwave software was used to simulate the optical propagation characteristics of the AWG,and results show that the channel spacing is 0.845 01 nm,the device insertion loss is less than 14 dB,and the crosstalk is less than-25 dB.
