STACKED COMPOUND PARABOLIC CONCENTRATORS INTEGRATED WITH MULTIPLE DIELECTRIC LAYERS FOR WIDE ACCEPTANCE ANGLE

摘要

The present disclosure relates to compound parabolic concentrators. In one implementation, a compound parabolic concentrator may include a parabolic array having a base, a side wall, and an aperture for receiving light and a dielectric layer having a refractive index. In another implementation, a stacked compound parabolic concentrator may include a parabolic array having a base, a side wall, and an aperture for receiving light and multiple dielectric layers within the array. Each dielectric layer may have a refractive index, and the refractive index may decrease with each dielectric layer moving from the base of the parabolic array to the light receiving aperture.
