Nanostructured Gradient Index Micro-Optical Components

摘要

Gradient Index (GRIN) lenses are an interesting alternative for conventional types of lenses. Instead of profiling the shape of the lens as it is done in conventional solutions, in GRIN lens the optical characteristics are achieved by a continuous variation of the refractive index within the lens material. Hence, as such lenses have plane surfaces they are easier for assemblage in the system developed based on optical fibers. This is one of the reasons why they are an interesting option for imaging and non-imaging optical systems.
