Home / Bracket fiber grating wavelength formula

This article explains what fiber Bragg gratings (FBGs) are: periodic modulations of the refractive index in a fiber core which reflect a narrow wavelength band according to the Bragg condition λ = 2 n eff Λ. The problem of finding solu-tions to the wave-propagation equations is simplified by assuming weak guidance, which allows the decomposition of the modes into an orthogonal set of. The optical bre or waveguide is presumed to have one mode of a xed polariza-tion. Calculate Bragg wavelength, reflection characteristics, and optimize FBG parameters for telecommunications, sensing, and laser applications.
