Abstract
An optical amplifier includes a chalcogenide glass optical waveguide having optical input and output ports, coupled to the chalcogenide glass optical waveguide, a pump optical waveguide, and a wavelength-tunable pump laser. The pump optical waveguide couples the wavelength-tunable pump laser to the chalcogenide glass optical waveguide.
