Abstract :
Reported is a photosensitive fibre for making long-period gratings with temperature sensitivity of the resonance wavelength as low as 0.25 nm over 0-70°C. Furthermore, a convenient method for selecting the temperature of minimum sensitivity, by controlling the boron concentration in the core and monitoring it with attenuation at 1550 nm, is presented.
