Fiber bragg grating as a uva sensor

Abstract

The idea of this paper implies the possibility to exploit the properties of graphene oxide (GO) to design a fiber Bragg grating (FBG) UVA radiation sensor. The idea assumes that a temperature change around the fiber can be induced by UVA radiation. UVA lighting will increase the internal energy of the GO and consequently locally raise the temperature on the surface of the optical fiber with an FBG sensor, changing the Bragg wavelength.
