ABSTRACT:
Disclosed is a nonfull aperture Luneburg-type lens for correction of an adjacent light source. The lens includes a core having a circular cross-section and a graded refractive index, and a cladding enclosing the core. The cladding has a circular cross-section and a homogenous refractive index. Also disclosed is a method for forming the nonfull aperture Luneburg-type lens with a graded index core and a homogenous cladding, and a high numerical aperture laser diode assembly including the nonfull aperture Luneburg-type lens.
