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. The box-type spectrum was constructed by reducing the core width of the odd-numbered arrayed waveguide and increasing the core width of the even-numbered arrayed waveguide. A fluorinated poly (arylene ether etheride) FPE polymer material was used to design and prepare a 17 × 17 channel box-type spectral response array Waveguide grating (WDM) wavelength division multiplexer.The test results show that the central wavelength of the device is 1550.87nm, the wavelength interval is 0.8nm, the 3dB bandwidth is about 0.476nm, the crosstalk is lower than -21dB and the insertion loss is 13 ~ 15dB.
