Abstract

In this paper we present the experimental comparison of mechanical and temperature sensitivities of Mach-Zehnder interferometer with replaceable FC connectorized sensing fibre arm, such as: off-the-shelf endlessly single mode microstructured fibre (MSF) or standard telecom single mode fibre. Experimental results clearly show reduced crosssensitivity to temperature of studied MSF compared with standard doped core fibre. Additionally, microstructured fibre Mach-Zehnder interferometer with standard FC receptacles allows using different fibres as sensors with the same device. Moreover, investigated interferometer consumes in total extremely low electric power (< 20 mW) and VCSEL as the light source.
