Tilted FBG
Description
Datasheet

The Tilted FBG has an angle between wave vector of the grating and fiber axis. Therefore cladding modes resonances peaks become more intensive compared to ordinary gratings. TFBG cladding modes resonances wavelength are highly sensitive to the refractive index of the medium outside the fiber cladding. TFBGs are useful in sensing applications. Possible value of tilt angle is 1⁰ - 45⁰.
