Tilted Fiber Bragg Gratings (TFBGs) present a refractive index modulation blazed by a few degrees in the plane perpendicular to the optical fiber axis. This results in two kinds of couplings: self-backward coupling of the core mode and numerous backward couplings between the core mode and the cladding modes. TFBG transmitted amplitude spectra are therefore characterized by several tens of cladding mode resonances that possess their own sensitivity to the surrounding refractive index (SRI).
