通过减少奇数阵列波导的芯宽度，同时增加偶数阵列波导的芯宽度的技术，构造了箱型光谱．选用氟化聚芳醚FPE聚合物材料，设计并制备了17×17信道箱型光谱响应阵列波导光栅（AWG）波分复用器．测试结果表明，器件的中心波长为1550．87nm，波长间隔为0．8nm，3dB带宽约为0．476nm，串扰低于-21dB，插入损耗为13～15dB．

英文摘要：

An efficient technique is used to flatten the spectral response of an arrayed waveguide grating （AWG） multiplexer. By subtracting an increment from the core width of odd arrayed waveguides and by adding the same increment to that of even arrayed waveguides,a box-like spectral response can be obtained. A 17 × 17 polymer AWG multiplexer with box- like spectral response has been made using FPE polymer materials. Measured result for the AWG shows that the box-like spectral response has a 3dB bandwidth of 0. 476nm, the crosstalk is about or less than - 21dB for every output channel,and the insertion loss is 13-15dB.
