| Abstract: | The novel characteristics of guided and surface wave modes in the chiral negative index cladding fibers were investigated theoretically.The characteristic equation of guided modes was derived.The dispersion curves,energy flux distribution and power curves of guided and surface wave modes were presented for three typical chiral negative index parameters.Some exotic features were found,such as two regions of single-mode operation exist,energy flux and power of surface wave mode are negative in dielectric fibe... |
