Abstract

See full text

Optically pumpable waveguide amplifier with amplifier having tapered input and output. The present invention provides for a optically pumpable waveguide amplification device that includes: a cladding material; a passive optical waveguide embedded in the cladding material that has no optical amplification functionality; and an active optical waveguide having an input portion, a middle portion and an output portion, including: a gain material with a higher refractive index than the passive optical waveguide, wherein the middle portion of the active optical waveguide is embedded in the cladding material, and faces the passive wave guide, such that a lower surface of the middle portion is an upper surface of the passive optical waveguide. There is also provided a device for optically pumpable waveguide amplification and a method for signal radiation amplification.
