Modal Analysis of Multidielectric Optical Fibers by Means of Least Square Method

We propose here to use the latter method, in the hypothesis of hybrid mode for multidielectric guides ( Cr >Crj>)Cr ) such that dielectric interfaces are distinct from equicoordinate surfaces. First we treated the simplest possible structure as shown in fig. 1. The results obtained in this case are shown to be identical to those already known in the case of cylinder dielectric waves uide with dielectric constant embedded into an homogeneous medium ( tamCr )
