Abstract
A method of fabricating an aspherical gradient refractive index lens includes co-extruding a first polymer material having a first refractive index and a second polymer material having a second refractive index different than the first refractive index to form multilayered polymer composite films, assembling the multilayered polymer composite films into a multilayer composite GRIN sheet and shaping the multilayered composite GRIN sheet into an aspherical lens.
