Abstract
An optical system includes a fiber-optic amplifier having a section of optical waveguide doped with a rare-earth element and a pump-light source for emitting pump light, the fiber-optic amplifier receiving signal light of a first wavelength and outputting at least signal light of a second wavelength. An optical-to-electrical transducer receives the signal light of the second wavelength from the fiber-optic amplifier and produces an electrical output signal. The signal light of the second wavelength is pump light which is unabsorbed in the section of optical waveguide.
