On Mode Spectrum Degenerations, Quasi-Degenerations and Mode Polarization Transformations in Optical Chiral Waveguides
Abstract
It is known 1-3, that mode spectrum degenerations take place for modes in chiral optical waveguides. Dispersion characteristics (curves) cross one another in the degeneration points, where propagation constants of two modes have the same values on some frequency. However, the more accurate analysis shows, that degeneration points are not exact but approximate only. In reality they are quasi-degeneration points. The dispersion curves do not cross one another, they close up near quasi-degeneration points. In this place, circular polarization of the modes converts: the right-handed polarization changes into left handed and on the contrary.
