| 摘 要： | 基于自准直效应,通过在二维空气柱型光子晶体非对称Mach-Zehnder干涉仪长臂上设置传感区域,设计了一种自准直传感器.平面波展开法确定了入射光的自准直频率范围,时域有限差分法分析了传感器的灵敏度达到68 nm/RIU,采用单频光入射实现了传感模拟.该传感器完全依赖自准直导光,无需引入任何缺陷波导,大大降低了制作工艺要求,其大小只有十几个微米,能够满足超紧凑、高灵敏度、廉价和无标记的要求. |

| Abstract: | A new asymmetric Mach-Zehnder interferometer sensor is proposed based on the self-collimation effect of two-dimensional air-cylinder photonic crystal by introducing a sensing area in the longer branch.Self-collimation frequency range is confirmed by employing the plane wave expansion method.Two-dimensional finite-difference time-domain technique is used in this work.68 nm/RIU sensitivity can be achieved.The simulated performance is realized by the incidence of single frequency light.The proposed photonic cr... |
