Paper Abstract

We prepared and demonstrated a compact, simple-to-fabricate, air microcavity in polydimethylsiloxane (PDMS), placed at the end of a single-mode optical fiber. The air microcavity creates a Fabry-Perot interferometer. The length of microcavity changes with change of temperature. So the wavelength shift of reference minima (maxima) of interference pattern corresponds to temperature change. For the operation of the sensor broadband light source and low-resolution optical spectral analyzer can be used. The sensor response for change of temperature is fast and occurs within a few seconds. The temperature sensitivity is 6.1 nm/°C. For optical spectral analyzer resolution 0.1 nm the smallest temperature difference possible to determine is 0.017 °C.
