Abstract
A process for manufacturing a preform from which is drawn an optical fiber, the core of which comprises layers of different glass composition. Layers of glass, adjacent ones of which have different composition, are deposited on a substrate. A process is preferred whereby layers of glass soot are deposited. The soot is consolidated and the resultant laminated glass structure is severed to form an elongated azimuthally asymmetric laminated core structure. A layer of cladding glass is added to the core structure, and the resultant preform is drawn into an optical fiber.
