Abstract :
It is shown, both theoretically and experimentally, that the pressure and temperature sensitivities of a fibre Bragg grating (FBG) can be increased by as much as 30 and 8 times, respectively, by coating the FBC with a polymer. A novel technique is then presented for coating an FBG with polymers so that a single FBG can be used for simultaneous measurement of pressure and temperature with good sensitivities
