Abstract

In this paper, we have demonstrated that the spectral bandwidth of a FBG can be modulated by embedding a single Fiber Bragg grating (FBG) sensor in a composite laminate. The bandwidth modulation was achieved by exploiting the birefringence of the embedded - FBG sensor, which was sensitive to the transverse strain and thus varies with temperature or axial load. Combining the bandwidth changes with the Bragg wavelength shift may enable measuring the simultaneous changes in temperature and axial strain using a single FBG sensor.
