Abstract

The invention belongs to the technical filed of up-conversion luminescence and optical waveguide devices, and specifically relates to a method for realizing light amplification of an optical waveguide device using an up-conversion luminescent material. According to the anti-Stokes luminescence principle, high-frequency short wave light is emitted by using low-frequency long-wavelength optical pumping, and furthermore, up-conversion luminescence is used to realize light amplification. The method can realize light amplification of light in ultraviolet, visible, and near-infrared light frequency ranges under infrared optical pumping. The method comprises: firstly, manufacturing an up-conversion luminescent material doped with sensitizer ions and luminescence center ions, and doping the up-conversion luminescent material in an organic or inorganic material through physical and chemical method, to manufacture a gain medium; and then using the gain medium to manufacture an optical waveguide device, motivating the up-conversion luminescent material by different pump light, to obtain up-conversion luminescence of each frequency range, and realizing light amplification in the optical waveguide device. The optical waveguide amplifier manufactured by the method can emit light in signal light wavelength through an up-conversion luminescence mechanism, so as to realize signal light gain.
