Abstract
An amplifying optical electromagnetic wave concentrator includes an amplification focusing device and a receiver. The amplification focusing device focuses an incident optical electromagnetic wave on the receiver. The amplification focusing device is doped with active components and is subjected to an excitation wave that causes the active components to pass to an energy level such that interaction between the incident electromagnetic wave and the active components causes the active components to pass to a lower energy level and causes emission, towards the receiver, of at least one photon having the same wavelength as the incident electromagnetic wave. The focused photon or photons form an amplified wave of the incident electromagnetic wave.
