Active aligning-fixing device and method for single-mode lens fiber and plate ridge-type waveguide

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...
