Background technology
Flourish along with the optical communication industry, optical lens has obtained the application of very big degree as requisite optical component in the optic communication device.Lens are realized the function to beam collimation or focusing in communication device.Existing is directly to utilize single lens to carry out active coupling with the single-mode laser coupled method, but because the angle of divergence of single-mode laser is large, hot spot with a tight waist is little, require signal-lens aligning and fixed precision usually less than 0.2um, its coupling and fixed precision are little, and as shown in Figure 1, packaging technology requires high, the actual production yield is low, and production efficiency is poor.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of lens combination for the single-mode laser coupling is provided.
Purpose of the present invention is achieved through the following technical solutions:
The lens combination that is used for the single-mode laser coupling, characteristics are: comprise laser instrument, first lens and the second lens, described first lens is coaxial lens with the second lens, and one times of focal length that described laser instrument is placed on described first lens is positioned on the focus of the second lens its virtual image that is become with interior.
Further, the above-mentioned lens combination that is used for the single-mode laser coupling also comprises: the first lens collar, the second lens collar, hollow sliding accessory and pedestal; Described first lens and the second lens place respectively in the first lens collar and the second lens collar, the described second lens collar is connected with the first lens collar by hollow sliding accessory, the described first lens collar is fixed on the pedestal, has the through hole relative with first lens on the described pedestal.
Further, the above-mentioned lens combination that is used for the single-mode laser coupling, the described first lens collar is fixed on the pedestal by the laser bonding mode.
Further, the above-mentioned lens combination that is used for the single-mode laser coupling, described hollow sliding accessory is connected with the second lens collar with the first lens collar by the laser bonding mode.
Again further, the above-mentioned lens combination that is used for the single-mode laser coupling, between described first lens and the first lens collar and between the second lens and the second lens collar by the metallic glass one-shot forming.
The substantive distinguishing features that technical solution of the present invention is outstanding and significant progressive being mainly reflected in:
The invention provides a kind of lens combination for single-mode laser coupling, by the design lens collar, hollow sliding accessory and pedestal etc., the first lens packaging passive alignment diminishes the angle of divergence of light beam, and hot spot with a tight waist becomes large, is easy to collimation; In addition, the coupling tolerance of its permission is large, also can reach high coupling efficiency under low alignment precision requires, and the coupling package feasibility greatly improves.
