Problems solved by technology

However, during the solder preparation process, the components will be heated, and at the same time need to adjust the optical coupling, which is not easy to operate; the micro-stress caused by the solder preparation process will gradually release, which will affect the optical performance and long-term stability; in addition, it must be used additionally Two metal casings and two glass casings, and the metal casing and the outer sealing tube need to be plated with gold to be tightly bonded to the solder, which will increase the overall component volume and material cost

Abstract

The invention includes a subcombination of optical fibre optical device with extended optical fibre, a ring cap, a sleeve and an external package pipe, a binding agent can be infiltrated into miniature gap between subcombination of said optical fibre optical device and all the components by utilizing capillary action so as to attain the goal of compact combination and sealed package. This combination mode is different from and superior to that of general optical component by using tin soldering paste.

Description

technical field [0001] The invention relates to a packaging method and structure of an optical device for optical fiber communication, in particular to a packaging method that uses capillary action to penetrate a bonding agent into a subassembly of an optical device and a small gap between each component to achieve dense bonding and sealing with structure. Background technique [0002] At present, the packaging of optical components for general optical fiber communication is mostly to use bonding agent to bond the optical components and necessary components together to form a sub-assembly (sub-assembly), and then package them into an integrally sealed product with soldering technology. figure 1 It shows a package cross-sectional view of a known optical add / drop filter manufactured by soldering technology, which first uses bonding agent to combine the components into a common port 30 and a pass port port) 31, and then combine the incident end 30 and the penetrating end 31 by...
