Abstract

An optical film including a plurality of structures formed from a material with each structure having a base, a first side wall that forms an acute angle with the base, and a second side wall that forms an obtuse angle with the base. The optical film efficiently couples light out of a light source or other structure. The optical film may be fabricated with a photolithographic process.
