WebWe consider a light signal propagating in a one-dimensional Bragg grating located in an SMF. The linear refractive index n of a uniform grating is given by where is the average refractive index, Δ n is the index modulation depth, and Λ is its period. For typical fiber gratings, and Δ n ≈ 0.01. To simplify the analysis, we usually assume that . WebNov 4, 2024 · Current testing methods are capable of measuring strain near the surface on structural parts, for example by using strain gauges. However, stress peaks often occur within the material and can only be approximated. An alternative strain measurement incorporates fibre-optical strain sensors (Fiber Bragg Gratings, FBG) which are able to …

Since λ is fixed by the incoming light you send, each n gives you a different angle θ n such that n λ = 2 d sin θ n. All of these secondary waves will be present because the incoming wave is scattered in all directions but only the directions θ n verifying the above equation will interfere constructively.
