摘　　要：分析了阵列波导光栅的结构、原理,并在Si基衬底上根据大折射率差的新型聚合物材料设计并制作了8×8的阵列波导光栅波分复用器件.波分复用器的中心波长为1551.4nm,输出波长间隔Δλ为0.8nm.制作的器件的插入损耗在中心波长处的测试结果约为9dB,相邻通道的串扰测量值小于-25dB.器件的尺寸为0.9cm×1.8cm.This paper overviews the AWG＇s structure and principle, and then reports a 8 × 8 polymer/Si arrayed waveguide grating which was designed and fabricated using new polymer materials with big refractive difference. The central wavelength of AWG is 1 551.4 nm, the wavelength spacing is 0. 8 nm. The inserting loss of the AWG is about 9dB for the central ports and the crosstalk level is less than-25 dB. The core size is much minimized, and it is only 0. 9 cm × 1.8 cm. This is very favorable for improving the integrated level of the integrated planar light wave circuit.
