Effect of the core size on the higher order modes of a chirofiber filled with different core and cladding chiralities

Abstract

The present paper discusses the properties of higher order modes (i.e. modes corresponding to a non-zero first modal index ν ≠ 0) for a chirofiber filled with different chiralities in the core and the cladding. The variation of the propagation constant β with the core radius shows a fluctuating nature for all these modes confirming and extending a prcviously reported result corresponding to ν = 0. The presence of chirality has the general effect of increasing the number of propagating modes that can be sustained.
