Optical fibre for fabricating long-period gratings with low temperature sensitivity within selected temperature range

This study reports a photosensitive fibre for making long-period gratings with temperature sensitivity of the resonance wavelength as low as 0.25 nm over 0 degree Celsius-70 degrees Celsius. Furthermore, a convenient method for selecting the temperature of minimum sensitivity, by controlling the bor...

Zusammenfassung:This study reports a photosensitive fibre for making long-period gratings with temperature sensitivity of the resonance wavelength as low as 0.25 nm over 0 degree Celsius-70 degrees Celsius. 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 1,550 nm, is presented.
