Abstract :
Measurements of the temperature dependence of the elasto optically induced optical activity in twisted single-mode fibres are reported. A simple method for providing temperature-free twisted single-mode fibres has been derived and successfully tested. Furthermore, we have constructed and tested a temperature sensor showing excellent linearity over the tested 20¿120°C range.
