Abstract

The invention belongs to the technical field of optical communication, and particularly relates to an optical waveguide amplifier and a preparation method thereof. The preparation method disclosed by the invention comprises the following steps: (1) processing a substrate to form a groove, wherein the substrate is porous glass with a three-dimensional communicated nanoscale pore channel structure; (2) transferring an erbium salt solution to the bottom of the groove, so that erbium ions are diffused into the porous glass to form an erbium-doped waveguide; and (3) depositing the erbium-doped waveguide to enable the erbium-doped waveguide to be sealed by a deposition material which is the same as the porous glass in material, and peforming sintering after deposition to obtain the optical waveguide amplifier. The doping concentration of Er < 3 + > is improved by utilizing the characteristics of the porous glass, the clustering effect of Er < 3 + > is inhibited, and the preparation stability of the optical waveguide amplifier is improved by utilizing a new method.

Description

Technical field [0001] The present invention belongs to the field of optical communication, and more particularly to a light waveguide array and a preparation method thereof. Background technique [0002] Signal light There is a certain loss and dispersion when transmitting in the fiber, which has seriously limited the transmission distance of the signal light. In order to ensure the transmission quality of the signal light, it is necessary to enhance the signal light, and the typical optical amplifier has a semiconductor optical amplifier, an optical fiber amplifier, and a light waveguide. The semiconductor optical amplifier is simple, the process matures, but the maximum weakness is too large, noise and crosstalk, noise and crosstalk and is susceptible to ambient temperature, so the stability is poor. The fiber amplifier has strong anti-interference ability, and the coupling loss is low, but the fiber amplifier is too long, which is not conducive to the miniaturization of the d...
