ABSTRACT:
An effective graded index profile optical fiber waveguide comprises alternating regions of high and low indexes of refraction of controlled thickness. The effective refractive index of the fiber has a graded profile of decreasing refractive index when the regions of high index have either a constant or decreasing thickness and the low index regions increase outwardly from the center. The effective refractive index has a particular graded profile of refractive index when the thicknesses of the regions of low refractive index and the high refractive index are appropriately chosen.
