Problems solved by technology

However, because silver nitrate has adverse factors such as photodecomposition under thermal conditions, the effect is not ideal.
[0003] Found through literature retrieval to prior art, the analysis of the erbium-doped glass Ag~+-Na~+ ion-exchanged optical waveguide that Mu Huan et al. This article introduces the research of optical waveguide film based on silver sodium ion exchange, but the defect is that it has not been protected from light, so the result is not very ideal

Embodiment Construction

[0013] The following embodiments are provided in conjunction with the accompanying drawings and technical solutions:

[0014] The substrate used in this example is erbium-ytterbium co-doped phosphate glass, the erbium-ytterbium doping concentration is 1%, silver nitrate and potassium nitrate are both chemically pure, the substrate length is 5 cm, first washed with water, and then vacuumed Film, sputtering, photolithography and other operations, so that 27 waveguide strip channels with different widths will appear. At the same time, salt compounding work is performed, and potassium nitrate and silver nitrate are mixed in a natural dark secret room according to the mass ratio of 8:1 For configuration, the total mass is 130 grams, stir evenly, and then pre-bake the waveguide sheet and the prepared salt in a far-infrared oven at 200 degrees for 24 hours to remove the moisture in it, then heat it up to 350 degrees, and stabilize it for 30 After 10 minutes, the waveguide sheet was p...

Abstract

The present invention first prepares exchange salt, adopting silver nitrate and potassium nitrate mixture, wherein the mass ratio of silver nitrate and potassium nitrate being 1: 8-1 : 10, uniformly stirring, preliminary drying waveguide piece and prepared salt in far infrared oven for removing moisture, then heating up to 350 degree centigrade, to proceed ion exchange by putting waveguide piece in melting salt, taking out waveguide piece and natural cooling, whole process being processed on lucifugal condition. The present invention reduces silver nitrate extent decomposition, raising waveguide surface ionic exchange quality, thereby improving made Erbium waveguide amplifier surface quality.

Description

technical field [0001] The invention relates to a method in the field of optical technology, in particular, to a method for using silver ions in the process of manufacturing an erbium waveguide amplifier. technical background [0002] Erbium waveguide amplifiers rely on pump light to pump short-distance active doped optical waveguides, using high concentrations of Er in the waveguide materials. 3+ The excited state energy levels of the particles work to generate integrated optical active devices that amplify the signal light transmitted in the waveguide. Glass passive waveguide devices (such as branched waveguides, polarization beam splitters, frequency division multiplexers, etc.) developed by ion exchange technology have the advantages of simple process, low cost, matching of refractive index and fiber, and easy integration. At the same time, it has the characteristics of small size, light weight, large amount of information, stable and reliable, anti-corrosion, anti-inte...
