A process for forming optical fibers with a graded refractive index profile includes the steps of applying a series of different monomolecular layers of different organic materials onto optically transparent fibers. The substrate has one refractive index and each subsequently deposited monomolecular film has an index of refraction which is lower, higher, or the same as the preceding material that it was deposited upon, thereby forming a graded refractive index of any desired profile. The process involves forming the plurality of monomolecular films by passing the fiber through a liquid monomolecular film interface to deposit each layer on the fiber. Typically, the liquid is water, and the monomolecular film is a fatty acid type material.
