| 摘 要： | 设计了一种阵列波导光栅解调集成系统中的8通道Si纳米线阵列波导光栅波分复用器。根据材料的折射率设计了单模波导截面尺寸,利用光束传播法对所设计阵列波导光栅进行了模拟。结果表明,器件尺寸为200μm×219μm,远小于目前技术较成熟的硅基SiO2的尺寸,光功率分布符合高斯分布,信道间隔为1.8nm,串扰小于-21dB。对小尺寸AWG的设计具有参考意义。

| Abstract: | An ultrasmall 8-channel array waveguide grating WDM device in AWG demodulation integrated system is designed,which is based on Si nanowire waveguides.According to the refractive index of material,the cross section size of a single-mode wave-guide is designed.AWG device is simulated with the beam propagation method.The results show that the device size is 200 μm×219 μm,far less than that of silicon-based SiO2 whose technology is more mature currently.Optical power distribution is in accordance with the gaussian distribution.The channel interval is 1.8 nm,crosstalk-loss is less than-21 dB. |
