To this end, the absolute value and the phase of the experimentally determined complex coupling coefficient are Fourier transformed separately, yielding a set of discrete lines that can be clearly identified and be traced back to cladding-modes. Removing these lines yields the grating properties in the absence of cladding-modes. © 2011 IEEE.en0733-872420111217831789OpticaCladding-modescoupling coefficientfiber Bragg gratings (FBGs)reflection factorTechnikIngenieurwissenschaftenJournal Article10.1109/JLT.2011.2141117Other
