Gauss-Laguerre modes parameters of curved optical fiber with coating

An approximate analytical solution for an arbitrary mode of a curved circle weakly guided fiber lightguide with an arbitrary refractive index profile is presented. It is takes into account the influence of the optical fiber coating on the mode parameters. The calculation results are presented for a typical refractive index profile of a multimode optical fiber with core and cladding diameters of 50/125. It has been shown that the presumption of the significant influence of the coating on the mode parameters of the weakly curved optical fiber has not been confirmed.
