TILTED FIBER BRAGG GRATING GTL-FBG-TL-860
Description
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. The TFBG transmission spectrum of 10mm length with tilt angle of 3⁰ is presented in the graph.

Frequently Asked Questions
A Tilted Fiber Bragg Grating (TFBG) is a type of fiber grating where the angle between the wave vector of the grating and the fiber axis is tilted. This results in more intensive cladding modes resonances compared to ordinary gratings.
Fiber Bragg Gratings (FBGs) have many applications in optical communication, laser techniques, and sensing systems. They can be used as in-fiber mirrors, optical filters with narrow band optical spectrum, and as sensitive elements for strain and temperature measuring.
The possible range of tilt angle for Tilted Fiber Bragg Gratings (TFBGs) is 1⁰ to 45⁰.
