摘要

We have studied the thermal response of the reflection wavelength of fibre Bragg gratings in polymer optical fibre to higher temperatures than previously reported. We observe a permanent shift in the wavelength once the grating is taken above a certain threshold temperature. This threshold can be shifted to higher temperatures by annealing the fibre before grating inscription, thus extending the working temperature range.
