Bragg's equation formula

Volume Bragg gratings (VBG) or volume holographic gratings (VHG) consist of a volume where there is a periodic change in the refractive index. Depending on the orientation of the modulation of the refractive index, VBG can be used either to transmit or reflect a small bandwidth of wavelengths. Bragg's law (adapted for volume hologram) dictates which wavelength will be diffracted: WebJul 8, 2024 · 1 Answer Sorted by: 2 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.
