Abstract

We report on the detailed analyses of mode coupling from fiber core to cladding in
excessively tilted fiber gratings (ETFGs). Cladding modes responsible for the typical dual peak
pairs in the transmission spectrum of ETFGs are identified with phase matching condition, which
suggests two set of dual peak pairs generated from coupling to cladding modes with even and
odd azimuthal order. The polarization dependence of those dual peak pairs are also investigated
by calculating the coupling coefficients of cladding modes for two orthogonal polarizations.
With the calculated coupling coefficients, the measured polarization dependent spectra can be
reproduced numerically.
