Problems solved by technology

But the process is cumbersome and the production efficiency is low
In addition, with ZrO 2 For ceramics, the accuracy of the distance between the holes is ±2μm. Due to the stress during processing, the crystal structure changes from tetragonal to monoclinic during sintering, which causes the connector to expand and affects the dimensional accuracy.
The optical fiber connectors and optical fiber array connectors prepared by these methods can be reinforced with adhesives after the optical fibers are inserted, and have a relatively simple operation, but the accuracy of the distance between the holes with more than two through holes and the array of through holes is affected. Influenced by various factors in metal mold manufacturing, forming, sintering and processing, it is very difficult to control the precision below 1 μm

Abstract

The invention discloses a fiber-optical array connector making method of optical communication, which comprises the following steps: combining the femtosecond laser illuminating and chemical disposal method to produce the array through-hole in the base plate; plugging and fixing the optical fiber in the through-hole to prepare the fiber-optical array connector. The method prevents the traditional method from preparing mould and sintering the blank, which simplifies the manufacturing technology and improves the gap precision.

Description

technical field [0001] The invention relates to optical communication, in particular to a method for manufacturing an optical fiber array connector for optical communication combined with femtosecond pulsed laser irradiation and chemical treatment. Background technique [0002] So far, the connectors and fiber array connectors used to fix optical fibers, connect optical fibers and optical communication components, and optical fibers are generally machined into V-shaped grooves on the surface of microcrystalline glass, silicon substrate, quartz glass, etc., or use ZrO 2 Ceramics are produced by using a metal mold as a blank, then sintered and finally machined to form the pores. The machining accuracy of the V-shaped groove is ±5μm. To ensure the accuracy of the V-shaped groove, it needs to be corrected by cutting and polishing. But the procedure is loaded down with trivial details, and production efficiency is low. In addition, with ZrO 2 For ceramics, the accuracy of the ...
