Abstract

An analytical study of the optical power confinement of a chirofiber is presented. Using Maxwell's field equations and considering the cases of meridional and skew modes, variation of the power confinement is presented in two events, viz. 1) with the change in cladding chirality (for fixed values of core chirality), and 2) with the change in core chirality (for fixed values of cladding chirality). Studies are made for two different fiber core diameters, and it is found that, in general, the power confinement in the core section reduces with the increase in its chirality admittance. Further, the amount of transmitted power increases with the mode index. However, as the core cross-sectional size increases, the skew modes present almost similar behavior, and the power transported by them is much higher as compared to that by the meridional modes. Thus, the skew modes in such chirofibers with a little larger size present an event close to degeneracy, which is useful in integrated-optic applications and optical-communication systems.
