Abstract

In this work an Intrinsic Fabry-Perot Interferometer (IFPI) based on an air-microcavity is presented. Here the air microcavity, with silica walls, is formed at a segment of a hollow core photonic crystal fiber (HCPCF), which is fusion spliced with a single mode fiber (SMF). Moreover, the spectral response of the IFPI is experimentally characterized and some results are provided. Finally, the viability to use the IFPI to implement a simple, compact size, and low cost refractive index sensor is briefly analyzed.

摘要

本工作提出了一种基于空气微腔的本征 Fabry-Perot 干涉仪 (IFPI)。这里的空气微腔由二氧化硅壁构成，形成于一段空心芯光子晶体光纤 (HCPCF) 中，该光纤与单模光纤 (SMF) 进行了熔融拼接。此外，还对 IFPI 的光谱响应进行了实验表征，并给出了一些结果。最后，简要分析了利用 IFPI 实现简单、紧凑且低成本折射率传感器的可行性。
