摘要

针对集成光子滤波器在3～5μm大气窗口波段的应用，文章提出了一种基于切趾光栅辅助反向耦合器（contra-DC）的中红外上下话路滤波器。采用互补光栅错位的方法进行相位调制，实现光谱旁瓣抑制，同时消除了传统光栅错位调制方法造成的光谱变形。仿真结果表明，文章所提器件可以实现22 dB的高旁瓣抑制比（SLSR），并且带通滤波谱顶部平坦，滤波谱线接近箱形。器件具有较低的插入损耗，直通端口插入损耗约为0.4 dB，下载端口插入损耗约为0.45 dB。

Abstract

Aiming at the problem of the application of the integrated photonic filter in the 3～5 μm atmospheric window banda mid-infrared add-drop filter based on the apodized grating-assisted contra-directional coupler (contra-DC) is studied and designed. The complementary lateral-misalignment method is used for phase modulation to achieve spectral sidelobe suppression and eliminate spectral distortion and broadening caused by the conventional lateral-misalignment modulation method. Simulation results show that the device can achieve a high Sidelobe Suppression Ratio (SLSR) of 22 dB

bandpass filter spectrum is flat at the top and the filtering spectrum is close to the box shape. The device has low insertion loss of about 0.4 dB through port and 0.45 dB drop port.
