Paper Abstract

A simple and new device to balance a Mach-Zehnder fibre interferometer has been develo-ped. It consists in a thermo-optical phase shifter (TPS) whose normalised phase response (sensitivity) is about 10-5 rad/m.K over an extremely large dynamic range (103). The advan-tages of the TPS compared to the conventional piezoelectric cylinder are discussed and the mode of operation of the TPS is described.
