Abstract
Gradient refractive index lenses (GRI-Ls) and methods of fabricating the same are provided. GRI-Ls can be fabricated by stereolithography (SLA) and/or photo-assisted, thermal-assisted, and/or other laser-based curing from at least two precursors with a preset refractive index gradation along the planar axis. These lenses are self-focusing lenses and may be convergent or divergent for decreasing and increasing refractive indices from the center, respectively. Rather than a gradation in lens thickness from the center, the GRI-Ls can have a gradation of composition from the center.
