High-speed optical waveguide switch chip packaging module

Abstract

The invention discloses a high-speed optical waveguide switch chip packaging module, and belongs to the field of optical packaging and radio frequency connection integrated modules. The optical waveguide chip comprises a light inlet waveguide, two light outlet waveguides, two grounding electrode plating layers and a radio frequency electrode plating layer; the first end of the metalized optical fiber penetrates into the accommodating cavity through the first end of the base and is coupled with the light inlet waveguide; the optical fiber array with the double-end connector comprises two bare optical fibers; the first radio frequency connection ceramic substrate comprises a first gold-plated layer, a second gold-plated layer and a third gold-plated layer positioned between the first gold-plated layer and the second gold-plated layer; the first SMA radio frequency connector is mounted outside the base; the second radio frequency connection ceramic substrate comprises a fourth gold-plated layer, a fifth gold-plated layer and a sixth gold-plated layer located between the fourth gold-plated layer and the fifth gold-plated layer; and the second SMA radio frequency connector is arranged outside the base. The structure is simple, and optical signals can be conveniently and directly input and output to the module.

Description

technical field [0001] The invention relates to the field of optical packaging and radio frequency connection integrated modules in optical fiber data communication and telecommunication, and mainly relates to a high-speed optical waveguide switch chip packaging module. Background technique [0002] The application of the optical switch module is an indispensable and important part in the optical fiber communication system. At present, the optical switch module generally refers to the function of realizing optical path conversion through an optical waveguide chip, a lens, an optical groove, and the like. Optical switches are generally divided into two categories: mechanical and non-mechanical. One of the non-mechanical types is the optical waveguide switch, which mainly changes the refractive index or other properties of the waveguide through the electro-optic effect, magneto-optic effect, acousto-optic effect, and thermo-optic effect, so that the optical path changes and t...
