Abstract

A three-branch integrated-optic Mach-Zehnder interferometer is proposed for the simultaneous measurement of pressures and temperature. A broadband source coupled with a spectrometer is used to perform phase measurements independently from transmission loss fluctuations. Fast Fourier transform techniques applied to the transmitted spectrum allow demultiplexing of the signal from each pair of branches. Various correlation criteria are applied to establish pressure and temperature values from fractional phase measurements.
