Abstract

The present invention provides an optical fiber pre-embedded type optical fiber array. The positioning groove of the optical fiber pre-embedded type optical fiber array is divided into a pre-embedded positioning section, a connection positioning section and a back installation positioning section; the connection positioning section is located between the pre-embedded positioning section and the back installation positioning section; a partition groove located between the pre-embedded positioning section and the connection positioning section is arranged on a substrate; and the connection positioning section is divided into a pre-embedded optical fiber section and pigtails, wherein the pre-embedded optical fiber section is fixed on the pre-embedded positioning section through a first adhesive, the pigtails are fixed through a second adhesive when being installed, and the pre-embedded optical fiber section can be also fixed in the positioning groove, the tail end of the pre-embedded optical fiber section protruding out from the positioning groove and being welded onto the pigtails. The present invention also provides an optical fiber array connection structure and a manufacturing method of an optical module. The optical fiber pre-embedded type optical fiber array, the optical fiber array connection structure and the manufacturing method of the optical module of the invention can be applied to a process in which an optical fiber array is automatically arranged onto a PCB in a surface-mount manner, and therefore, the production efficiency and cost competitiveness of optical fiber communication components can be greatly enhanced; the optical fiber pre-embedded type optical fiber array, the optical fiber array connection structure and the manufacturing method of the optical module are suitable for large-scale mass production; and the optical performance and thermal stability of the optical fiber pre-embedded type optical fiber array can be comparable to that of a 45-degree FA (fiber array).

Description

technical field [0001] The invention relates to an optical element in the field of optical fiber communication, in particular to a method for manufacturing a precisely positioned optical fiber array and an optical module. Background technique [0002] Because the fiber array can precisely position the fiber, it becomes an important coupling component between the optical device and the fiber, and is widely used in the production of optical communication devices, such as planar optical waveguides, arrayed waveguide gratings, micro-electromechanical systems, and multi-channel optical modules. Wait. [0003] In the optical transceiver module, there are mainly two coupling schemes: plastic lens array and 45°FA (fiber array). 45°FA can be successfully applied to low-speed products below 10G and high-speed products of 40G and 100G at the same time because it is very well matched with VCSEL (vertical surface emitting laser source) array and PD (photodetector) array. However, since...
