Paper Abstract

Recently, an ultraviolet (UV) sensor based on a photomechanically responsible material and a fiber Bragg grating (FBG) has been proposed by our group. The elasticity of the azobenzene polymer as a photo-responsive material is changed by UV light, which induces a center wavelength shift corresponding to the variation in the azobenzene-coated FBG's period. In this study, we test the performance and reliability of the abovementioned sensor.
