Abstract:
In this paper we consider the use of a one-dimensional fractional Fourier transform for gradient-index optical waveguides. We calculate eigenfunctions of the transform in view of a limited range in the spatial and spectral domain.

Keywords:
fractional Fourier transform, bounded paraxial operator, eigenfunctions, Hermite-Gaussian modes, spheroidal wave functions.
