Fast and Simple Method for Evaluation of Polarization Correction to Propagation Constant of Arbitrary Order Guided Modes in Optical Fibers with Arbitrary Refractive Index Profile

Figure 2

Error reducing of calculation of the higher order mode HE21 normalized propagation constant produced by EMGA by polarization correction under low value of normalized frequency: (a) relative error, with and without polarization correction; (b) difference of relative error curves.
