Abstract

Abstract A highly doped optical amplifier in the form of a thin layer or fiber wherein the pump light is directed transversely to the surface of the layer or fiber. A transparent substrate is provided underneath the layer or fiber and a solar cell is provided in light receiving relationship to light passing through the layer or fiber on the opposite side of the substrate.
