CONDUCTING SHEATH HELICAL WINDING ON THE CORE-CLADDING INTERFACE OF A LIGHTGUIDE HAVING A PIET HEIN SUPER ELLIPTICAL CORE CROSS-SECTION AND A STANDARD OPTICAL FIBER OF CIRCULAR CROSS-SECTION-A COMPARATIVE MODAL ANALYSIS

In this article, a theoretical and computational analysis has been made to obtain the modal dispersion characteristics of an unconventional optical waveguide with a Piet Hein core cross section having a conducting sheath helix winding on its core-cladding
