Tilted FBG
Description
Datasheet
Tilted Fiber Bragg Gratings feature an angle between the grating’s wave vector and the fiber axis. This tilt causes the cladding mode resonance peaks to become more intense compared to standard Fiber Bragg Gratings. The resonance wavelengths of TFBG cladding modes are highly sensitive to changes in the refractive index of the surrounding medium outside the fiber cladding.
Due to this sensitivity, Tilted Fiber Bragg Gratings are widely used in optical sensing applications, including environmental monitoring and biochemical sensing. The typical tilt angle of TFBGs ranges from 1° to 45°, allowing customization based on specific sensing requirements.
