Embodiment Construction

[0038] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0039] With reference to accompanying drawing 1,2 and 3, make the active aligning fixture of single-mode lens fiber and planar ridge waveguide of the present invention. Referring first to Figure 1, the laser 1 is a near-infrared continuous tunable laser with a continuous output wavelength of 1500nm-1640nm and a maximum output power of 10mW, such as the product of GN Nettest in Japan. The single-mode lens input and output fibers 2 and 14 are near-infrared single-mode lens fibers, conical, with a curvature radius of 8-9 μm, a cone angle of 55-56 degrees, and a working distance of 4-5 μm. Products sold in the market can be purchased, such as Products produced by Wuhan Chuxing Optical Fiber Application Technology Co., Ltd. The first adjusting frame 4 adopts products sold in the market, such as the electric six-dimensional precision adjusting frame ...

Abstract

The invention discloses an active alignment fixing apparatus and method of haplotype lens optical fiber and plate ridge waveguide. The device includes: laser device, haplotype lens input optical fiber, optical fiber transporter, optical fiber anchor, adjustable bracket, optical fiber adjustable groove, glass base, waveguide sample, haplotype lens output optical fiber and optical dynamometer and so on. The method includes following steps: 1) the haplotype lens input optical fiber is fixed on the optical fiber transporter; 2) the optical fiber transporter is fixed on the first adjustable bracket; 3) the glass base is fixed with the optical fiber adjustable groove; 4) the plate ridge waveguide sample is mounted on the base; (5) the haplotype lens output optical fiber is mounted on the second adjustable bracket, and align with the plate ridge waveguide sample; 6) the fixing course of coarse alignment; 7) the fixing course of accurate alignment; 8) the alignment is finished. The alignment fixing of the invention possesses high coupling efficiency and stability, and it can reduce the operation difficulty and technical cost, and reach lossless detachment and reutilization.

Description

technical field [0001] The invention relates to an alignment and fixing device and method for a single-mode optical fiber and a slab waveguide, in particular to an active alignment and fixing device and method for a single-mode lens fiber and a slab ridge waveguide. Background technique [0002] The alignment and fixation of single-mode optical fiber and slab ridge waveguide has an important position in the field of optical fiber communication. Since the 1970s, people have begun to study this work. In the document "Single Mode Fiber-To-Channel Waveguide Coupling" published by J.Opt.Comm.2.122 (1981), Ramer discussed the coupling problem between single-mode fiber and planar ridge waveguide. In order to improve the coupling efficiency of single-mode fiber and waveguide, the following three methods are usually used: ① microlens is added between single-mode fiber and waveguide; ② waveguide is designed as a graded waveguide; ③ input fiber is single-mode lens fiber. Among these t...
