WAVEFRONT FORMATION IN LONGITUDINALLY NONUNIFORM ASYMMETRIC GRADIENT WAVEGUIDES
A. B. Valyaev, S. G. Krivoshlykov
A new refractive index reference profile is suggested for describing asymmetric gradient waveguides. The effect of regular longitudinal non-uniformities on the wavefront of beam in these waveguides is studied. Relations have been determined for estimating the field amplitude across the beam at the interface of two such waveguides. The possibility is demonstrated of determining medium parameters through the known characteristics of the primary and final beams.
