Optical characteristics of fibers with negative refractive and zero refractive index

Abstract

Abstract:

The optical characteristics of guided modes in a fiber formed by a core with usual refractive index and a negative refractive index cladding are studied, the difference compared with normal fiber is analyzed through the dispersion curves showing less degenerate modes and larger single-mode area.When the cladding refractive index tends to zero ,the optical characteristics are different from the former two fibers. A single-mode in the smaller region V is found ,when the permittivity or permeability of the cladding is zero.It is quite different from the mode HE11 in a normal fiber, its dispersive curve has an opposite tendency, and there are some areas where no modes could exist .

Key words: fiber and waveguide optics, negative refractive index, zero refractive index, single mode
