设计了基于绝缘层上硅(SOI)平坦化阵列波导光栅单纤三向器.三向器三个波长(1310,1490和1550nm)工作在阵列波导光栅的三个不同的衍射级数,并在阵列波导光栅的输入波导末端引入多模干涉器(MMI),实现了平坦响应的三波长波分复用.模拟结果表明基于这一设计的三向器3dB带宽为6nm,串扰小于-40dB,插损为5dB.制备的三向器经测试输出光场清晰,实现了三向器的功能.

Triplexers are designed based on SOI flattop arrayed waveguide gratings (AWGs).Three wavelengths (1310.1490,and 1550nm) operate at three diffraction orders of AWGS.Simulation shows that the 3dB bandwidth,crosstalk,and loss are 6nm,less than-40dB,and 5dB,respectively.The output optical fields of the device fabricated in our laboratory are clear and show a good triplexing function.
