Silver ion use method for erbium waveguide amplifier making process

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 production process of an erbium waveguide amplifier. technical background [0002] The erbium waveguide amplifier relies on the pump light to pump the short-distance active doped optical waveguide, and utilizes the high concentration Er in the waveguide material 3+ The excited state energy level of the particle works, so that the signal light transmitted in the waveguide produces an integrated optical active device that amplifies. Glass passive waveguide devices (such as branch 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 optical fiber, and easy integration. At the same time, it has the characteristics of small size, light weight, large amount of information, stable and reliabl...

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
