声光子晶体微腔的光声传感特性

声光子晶体是一种同时具有光子和声子带隙的人工微结构, 因此可实现对光和声的同时操控, 在腔光力学及声光功能器件领域展现了广阔的应用前景。本文基于有限元数值计算方法, 研究了声光子晶体微腔的光声传感特性。研究结果表明, 通过简单地引入点缺陷, 声光子晶体不仅能很好地实现对光和声场的同时局域, 而且能同时获得光及声信号的高灵敏度传感, 光、声传感灵敏度分别达到了277 nm／RIU, 275 MHz／ms-1。由于光和声两个物理量能同时并独立地实现高灵敏度传感, 因此该种传感器能应用于更为复杂的生化传感。

Abstract

Phoxonic crystal (PhXCs) is a kind of artificial microstructure which has both photonic and phononic band gaps.Thus PhXCs can simultaneously tailor electromagnetic and elastic waves with potential applications for highly controllable photon-phonon interactions and acousto-optical devices.The sensing characteristic of PhXCs microcavity is investigated via the finite element method.By calculating the light and acoustic transmission spectrum, phoxonic sensitivity is obtained.The research results show PhXCs can simultaneously not only confine optical and acoustic waves, but also provide high sensitivity to optical and acoustic waves by simply introducing a point defect into a perfect PhXCs.The optical sensitivity and acoustic sensitivity reaches 277 nm／RIU, 275 MHz／ms-1 respectively.This kind sensor can deal with complex analytes for biosystems due to the fact that it can determine two independent physical properties simultaneously.
