ABSTRACT:
Disclosed is an optical waveguide fiber having a core surrounded by a layer of cladding material. The core is characterized in that it includes a region of depressed refractive index. The inner radius a.sub.i of this region is greater than zero, and the outer radius a.sub.o thereof is less than the core radius. By appropriately selecting the core index depression characteristics such as radial location, width, depth and shape, a fiber having the desired waveguide dispersion characteristics can be designed. Dispersion minimization over a wide wavelength range can be achieved, without adverse effect on system loss.
