实验证明，在非对称迈克尔逊干涉仪传感器中，慢波增强了相位和光谱灵敏度，其相位灵敏度为277,750 rad/RIU-cm，理论相位灵敏度高达461,810 rad/RIU-cm。在低成本芯片集成光子封装传感器的背景下，我们将在实验中展示一种使用相变材料来主动调谐干涉仪条纹的方法，该方法将潜在地克服制造引起的干涉条纹波长的变化，从而允许传感器芯片封装成固定波长的激光器和可用的集成光电探测器。
We experimentally demonstrated slow wave enhanced phase and spectral sensitivity in asymmetric Michelson interferometer sensors with a phase sensitivity 277,750 rad/RIU-cm and theoretical phase sensitivity as high as 461,810 rad/RIU-cm. In the context of low-cost chip integrated photonic packaged sensors, in this paper we will experimentally demonstrate a method for active tuning of interferometer fringes using phase change materials that will potentially overcome fabrication induced variation of interference fringe wavelengths, thus allowing sensor chip packaging with a fixed wavelength laser and available integrated photodetectors.
