| 摘 要： | 依据阵列波导光栅(AWG)的传输理论,在中心波长为1550.918 nm、波长间隔为0.8nm的条件下,对33×33信道聚合物AWG波分复用器进行了参数优化,分析了阵列波导的弯曲对器件传输性能的影响。分析结果表明,波导的弯曲将使AWG中的传输光产生相移,引起传输光谱的漂移和串扰的改变。本文所设计的AWG器件的光谱漂移约为0.01 nm,远远小于波长间隔0.8 nm,串扰的变化也很小。

| Abstract: | Based on the transmission theory of the arrayed waveguide grating(AWG),the parameter optimization was performed,and the effect of arrayed waveguides bending on transmission characteristics was analyzed for a 33×33 polymeric AWG multiplexer around the central wavelength of 1550.918 nm with the wavelength spacing of 0.8 nm.The analytical results show that the bending of arrayed waveguides causes the phase shift of the light propagating in the AWG, results in the shift of the transmission spectrum,and brings about the variation of the crosstalk.For the designed AWG device,the shift of the transmission spectrum is about 0.01 nm,which is much less than the wavelength spacing of 0.8 nm,and the variation of crosstalk is also little. |
