摘要： An integrated waveguide device for optical signal amplification employing a low-cost and high-power type source of pump light selected from the group composed of broad band LEDs and broad area laser diodes. The integrated device has an active core (3) made of silica, silicon based dielectric material, or multicomponent glass,' containing at least a uniformly dispersed sensitizer element selected out of silicon nanoclusters and Ytterbium ions and ions of a rare- earth able for producing a stimulated emission within a certain wavelength band. The device comprises: a substrate (1) of a material suitable for defining thereon integrated planar waveguide structures; an optical signal waveguide (2) on the substrate for single mode guiding one or more optical signals, including an active core of the above composition with a first refractive index n 1 and at least an inner cladding (4) of dielectric material having, a second refractive index n 2 lower than n l;a waveguide adapted for multimode guiding the pump light extending adjacently to the single mode optical waveguide; means for coupling pump light from the source (5) to the multimode optical waveguide.
