Problems solved by technology

[0003] Due to the limitations of the processing technology, the light cone formed by the blank after the stretching process can only be a single straight zone light cone; that is, the extension direction of the optical fiber in the large end surface area of ​​​​the light cone is parallel to the axis of the light cone, while The angle between the extension direction of the optical fiber in the small end face area and the axis of the light cone is an acute angle (at present, the angle between the small end face of the general light cone and the axis of the light cone is mostly 30°-70°); in practical applications It has been verified that the existing single straight zone light cone can no longer meet the application requirements in terms of coupling efficiency and high-quality resolution.

Abstract

The present application provides a processing method of an optical fiber taper. The aforementioned optical fiber taper includes a large end face, a small end face and a smooth transition portion; the smooth transition portion is located between the large end face and the small end face; Each optical fiber extends from the large end face and the smooth transition portion to the small end face; on the large end face, each optical fiber is arranged in parallel; on the small end face, each optical fiber is arranged in parallel. In the optical fiber taper provided by the application, each optical fiber is arranged in parallel in the large end face and the small end face. Compared with the existing single straight zone light taper, the optical fiber taper is installed in the optical device, and is compatible with the optical fiber taper. Better coupling efficiency between other optics in the device.

Description

technical field [0001] The present application relates to the technical field of optical devices, in particular to a processing method of an optical fiber taper. Background technique [0002] Optical fiber cone (hereinafter referred to as light cone) is an optical device made of a large number of optical fibers through regular arrangement, heating, pressure fusion and stretching process; because the light cone has the function of magnifying and reducing the image by a specific factor, and can obtain The object image distance is very small, so it becomes one of the core components of image enhancement devices, and is widely used in miniaturized image equipment and image digitization equipment. [0003] Due to the limitations of the processing technology, the light cone formed by the blank after the stretching process can only be a single straight zone light cone; that is, the extension direction of the optical fiber in the large end surface area of ​​​​the light cone is paral...
