“…This can be appreciated clearly in Figure 5(a,d), where less ‘intense’ peaks appear over the well-defined FPI fringes. This superposed FPI spectrum can be explained by the effect of multiple reflections occurring in the FPI mirrors [20–22], in this case within the silica wall. Furthermore, in order to these multiple reflections occurs within the silica wall it sides must be quasi parallel [20,23] at its central region.…”

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.
