In this work, a multi-parameter point sensor based
on the combination of Fabry-Perot (FP) and the anti-resonant
(AR) reflecting guidance in cascade configuration is proposed and
experimentally demonstrated. This structure, based on FP
interference and AR reflecting guidance, was fabricated with two
different air micro-cavities. The attained experimental results
showed different strain and temperature sensitivities for the
antiresonance contribution. However, when analyzing the FP
interference, only strain sensitivity was observed, demonstrating
that this air micro-cavity was also insensitive to temperature
variations.
