A Rigid-Flexible Hybrid Fiber Fixture with Two-Dimensional Attitude Adjustment Function

Abstract

The present invention discloses a rigid-flexible mixing optical fiber clamp with a two-dimensional attitude adjustment function. The rigid-flexible mixing optical fiber clamp comprises a two-dimensional adjustment structure, a rack is arranged at the inner concave of the lower portion of the clamp, an optical fiber putting groove is designed at the end portion of the front end of the clamp, an optical fiber pigtail block is arranged in the groove and is compacted by an optical fiber pressing plate, and the pressure of the optical fiber pressing plate is adjustable. The rack is connected with the two-dimensional adjustment structure through a flexible hinge to allow the pitching angle of the two-dimensional adjustment structure to be adjustable; the lower portion of the rack is provided with a deflection sliding plate, and the rack and the deflection sliding plate can be relatively rotated to achieve adjustment of the deflection angle of the two-dimensional adjustment structure. The lower portion of the deflection angle is provided with a fixing mechanism to achieve connection between the fixing mechanism and a waveguide chip coupling displacement bench. Long circular holes are arranged on the deflection sliding plate, a fixed substrate and a substrate sliding plate in X, Y and Z directions to achieve position regulation of the two-dimensional adjustment structure on a triaxialdirection. The rigid-flexible mixing optical fiber clamp can flexibly adjust the optical fiber clamping pressure and the installation position of the optical fiber clamp, and a serial three-dimensional translation platform with a two-dimensional attitude adjustment function and a one-dimensional rotation table can achieve six-dimensional pose adjustment of the optical fiber.

Description

Technical field [0001] The invention relates to an optical fiber clamp, in particular to a rigid-flexible hybrid optical fiber clamp with a two-dimensional posture adjustment function. Background technique [0002] Integrated optical waveguide device, abbreviated as optical waveguide device, is an optical device based on guided wave optics theory and microelectronic processing technology. Because of its small size and high density, it is widely used in optical fiber communications, optical fiber sensing and other fields. [0003] The production of optical waveguide devices mainly includes the production of optical waveguide chips and the coupling and packaging of optical waveguide devices. The coupling package of the optical waveguide device is divided into the posture alignment of the waveguide chip and the optical fiber and the fixed connection after alignment. The position alignment of the waveguide chip and the optical fiber requires the optical fiber to be installed and clamp...

AI Technical Summary

Problems solved by technology

As mentioned above, the alignment requirements between the optical waveguide chip and the optical fiber are at the micron or sub-micron level, and it is necessary to use a high-precision motion platform to realize the adjustment of the position and orientation of the optical fiber. Precision motion platforms are mostly dependent on imports, resulting in high production costs for optical waveguide devices

In addition, due to the brittle material of lithium niobate, the existing optical fiber clamps have the disadvantages of being easily broken or not tightly clamped, which further increases the difficulty of optical fiber clamp design
