A detailed analysis of tapered and inhomogeneous dielectric light collectors was worked out for both illumination and solar energy applications. In particular, tapered dielectric guides have been investigated both theoretically and experimentally together with their capability to collect and transmit high fluxes of light energy. Furthermore, GRIN rods are considered as matching devices, to improve the collecting performance of tapered guides.
