A method of fabricating an optical fiber collimator array

Abstract

The invention relates to the field of optical communication, provides a manufacturing method of an optical fiber collimator array, and solves the technical problems that the optical axis direction of the emergent light of the optical fiber collimator array can be accurately ensured to be consistent in a low cost way and the position is accurate. The optical fiber collimator array comprises a pedestal equipped with array installing holes and optical fiber collimators. The optical fiber collimators are installed on the pedestal through one-to-one corresponding adjustment with reference collimators, and the angle of all the optical fiber collimators is adjusted to be consistent with that of the reference collimators so that the emergent light beams of the optical fiber collimator array can be mutually parallel. The optical fiber collimators are fixed in the installing holes of the pedestal through the binder and heating is performed through a heating ring in the curing process of the binder so that the objectives of accelerating curing and releasing stress in the heating process can be achieved. The manufacturing method of the optical fiber collimator array is simple in structure, low in cost and high in operability and can be widely applied to the array collimator structure of the multichannel optical communication system.

Description

technical field [0001] The invention belongs to the field of optical communication, and in particular relates to a manufacturing method of an optical fiber collimator array. Background technique [0002] With the rapid growth of modern communication data, communication requires more optical paths to transmit data at the same time than before, so higher requirements are placed on the bandwidth and capacity of communication. In order to meet this requirement, multi-core fiber collimator arrays are used in many optical devices. However, the fiber collimator array has relatively high requirements on the accuracy of the components and the processing and assembly technology, and it is necessary to ensure the parallelism between the outgoing beams in the fiber collimator array, as well as the accuracy of the position and the direction of the optical axis. At present, two production methods are generally used in the market to ensure the above characteristics of the fiber collimator...

AI Technical Summary

Problems solved by technology

In the first method, in order to ensure that the beams are parallel to each other, the spacing tolerance between the array optical fibers and the spacing tolerance between the array lenses must reach the order of microns, which requires high processing accuracy of the material components, making the material processing Complex, relatively high cost, and limited by the process of the array lens, the generally made fiber collimator array has a short working distance

Although the second method reduces the processing accuracy requirements for material components, since the collimators are fixed separately, it is difficult to avoid the position shift of some collimators during the manufacturing process or the stress release process in the later stage. The craftsmanship has high requirements, and the problem of short working distance has not been well solved
