Abstract
The invention discloses a method for improving the coupling stability of an optical active device, which is characterized by comprising the following steps of: coupling a semiconductor laser and an optical fiber to a focal point during coupling alignment; and moving the optical fiber to the semiconductor laser, so that a fiber core inlet of the optical fiber is positioned in the focal point of a light beam of the semiconductor laser, and the width of the light beam is greater than the diameter of a fiber core; therefore, the coupling stability of the optical active device is improved.
Description
Technical field
The present invention relates to a kind of optics method, particularly a kind of method that improves optical active component coupling stability.
Background technology
Along with world's development of information industry; Fibre Optical Communication Technology is being brought into play important role as the core technology of information age at aspects such as voice communication, video transmission, exchanges data, Internet of Things; And optical active component is as the core component of optical fiber communication, and its performance of products stability directly has influence on the quality of communications.In most of the cases; Light emission or receiving device need be coupled and aligned with optical fiber, and are to guarantee the maximum optical coupling efficiency when being coupled and aligned, and utilize optical imaging system; For example lens image in fiber cores with the photelectric receiver light-sensitive surface or the light emitting devices surface of emission.But because the receiving plane and the fiber cores of the optical transmitting set surface of emission or receiver are all very little, when device is influenced by external force or under high and low temperature, move, connect the deformation that external metallization structural member or solder joint produce, its coupling efficiency can change very responsive to relative position.
Therefore, need a kind of new technical scheme to address the above problem.
Summary of the invention
To above-mentioned existing in prior technology problem and shortage, the purpose of this invention is to provide a kind of method that improves optical active component coupling stability.
For realizing above-mentioned purpose, the method that the present invention improves optical active component coupling stability can adopt following technical scheme:
A kind of method that improves optical active component coupling stability; When being coupled and aligned, earlier semiconductor laser and optical fiber are coupled to focus; Then optical fiber is moved to the semiconductor laser direction; Make the fibre core entry position of optical fiber be positioned at the semiconductor laser beam focus, make the width of light beam greater than the diameter of fibre core, thereby improve optical active component coupling stability.
The present invention is compared with prior art: the width of light beam is greater than the diameter of fibre core, thereby improves the stability that optical device changes outside hardware.
Description of drawings
The apparatus assembly synoptic diagram of Fig. 1 for adopting among the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment; Further illustrate the present invention; Should understand following embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Please combine shown in Figure 1ly, the present invention discloses a kind of method that improves optical active component coupling stability, when being coupled and aligned, earlier semiconductor laser 20 and optical fiber 30 is coupled to focus, makes that its coupling efficiency is maximum, optical output power is the highest; Then optical fiber 30 is moved to semiconductor laser 20 directions; Make its output descend; But still satisfy the product index requirement and leave certain surplus; Make fibre core 31 entry positions of optical fiber 30 be positioned at semiconductor laser 20 light beam A focuses, make the width of light beam A greater than the diameter of fibre core 31, thereby improve optical active component coupling stability.The optical device that at last completion is coupled and aligned welds fixing getting final product.The present invention is not reducing the work survival rate; Do not increase under the situation of raw materials consumption, strengthened facula area, reduced the susceptibility of optical fiber; Improved the stability that optical device changes outside hardware; Reduce bad ratio in the manufacture process, reduced manufacturing cost, guaranteed the long-term stability of product.In the present invention, except that adopting semiconductor laser, also can adopt other photoelectric devices and optical fiber to be coupled and reach of the present invention as the photoelectric device.Method of the present invention realizes improving the purpose of coupling stability.
