Abstract :
A new method is presented for the passive temperature compensation of piezo-tunable fibre Bragg gratings using the negative thermal expansion coefficient of the low voltage piezoelectric ceramic. A centre wavelength shift of only 0.5 pm/K over a wide range from -10 to 60°C has been shown experimentally
