HIGHLY NON-LINEAR SINGLE MODE WAVEGUIDE

摘要

Disclosed is a single mode optical waveguide fiber having a core region refractive index profile designed to provide a highly non-linear refractive index. The core index profile of the highly non-linear waveguide is an alpha -profile which has pre-selected values of relative refractive index and core diameter so as to retain the advantageous optical waveguide properties of low attenuation, properly placed zero dispersion and cut off wavelengths, low, positive total dispersion over a pre-selected wavelength range, and low dispersion slope.
