Abstract :
A new approach to measure relative humidity changes by using fiber Bragg grating (FBG) is presented. Etching method is used to fabricate an FBG taper. The sensitivity of the FBG sensor for relative humidity change is 0.0014 dB/% and the linearity value which is the measure of the goodness of fit is 98%. The wavelength shift with respect to relative humidity is measured to be 0.00268 nm/%.
