Optical fiber waveguide having minimum modal dispersion

Abstract From the Canadian patent

Abstract of the Disclosure, A graded index optical fiber waveguide for use in an optical communication system is disclosed. The waveguide is a circular symmetric fiber having a cladding With an index of refraction n2 surrounding a core whose index of refraction is graded from an on axis value of n1 to a value of n2 at the core-cladding interface. The index of refraction within the core is defined on terms of a profile function F by the following equation n2 = n?(1-F), where F is O on the axis and a function of the radial coordinate r and wavelength A within the core and satisfies the following equation, where D is a function of A having a value approximately equal to F for minimum modal …
