Measurement Science and Technolgy, 2002, Vol. 13, No. 5, pp792-7950957-0233http://dx.doi.org/10.1088/0957-0233/13/5/318http://dspace.lib.cranfield.ac.uk/handle/1826/1415Surrounding a long period grating, fabricated in a standard optical fibre, with a material with a high thermo-optic coefficient enhances the temperature sensitivity of a long period grating. Temperature sensitivities as high as 19nm/°C are reported over a temperature range of 1.1°. The temperatures at which the LPG exhibits enhanced sensitivity may be tailored by a suitable choice of material.en-UKFibre opticsFibre optic sensorsLong period gratingArticle
