WebThe Bragg wavelength ( λB ) is defined as λ B = 2 ne Λ where 2ne is the effective reflective index of the grating in the fiber, and Λ is the grating period. The grating period is the space between each change in the refractive index. Important to note that the Bragg wavelength of an FBG can be anything.
WebDec 8, 2010 · The reflected wavelength is called the Bragg wavelength and is influenced by the strain and temperature applied to the FBG. An FBG with a Bragg wavelength of 1.55 μm has sensitivities to strain and temperatures of 14 pm/K and 1.2 pm/με, respectively [ 1 ]. WebBragg's Law is represented in the following formula: nλ = 2dsinθ where: (λ) wavelength of x-ray (n) order of diffraction (d) distance between layers of atoms (θ) the angle of …
