Optical coupling solid optical taper

Abstract

The invention relates to a light coupling solid-core light cone. The light coupling solid-core light cone is made of quartz materials and has two end surfaces with the different diameters, and a bus of a cone body of the light core consists of three sections, which is a straight line, an arbitrary smooth curve and the straight line respectively. The light coupling solid-core light cone of the invention has good light transmission performance, small light energy loss, simple and reasonable structure, easy manufacture and low cost, thus being applicable to the light beam receiving, aggregation of free-space light, coupling between a light source and an optical fiber and other occasions in the wireless optical communication.

Description

technical field [0001] The invention relates to an optical coupling solid light cone, which is suitable for light beam reception in wireless optical communication, light gathering in free space, coupling between a light source and an optical fiber, and the like. Background technique [0002] Due to the requirement of high-speed data transmission in modern communication, optical fiber is gradually applied to the optical receiving system of wireless optical communication. The coupling efficiency of received light and optical fiber directly affects the reliability of data communication, and is the key to the optical receiving system of wireless optical communication. Therefore, the more light energy that enters the fiber, the better.

AI Technical Summary

Problems solved by technology

[0003] In order to couple as much light as possible from the transmitting end into the receiving optical fiber, an optical receiving system is often used to focus the light, but the cost of the optical system is high and the maintenance is difficult; the conversion efficiency is low and the guide beam is used for convergence. The number of beams is large, and it is difficult to connect with subsequent equipment

In addition, the external environment often causes the jitter of the transmitted light beam, which in turn leads to the drift of the image point at the light receiving end. Using a large-aperture fiber can solve the image point shift in a small range, but in the case of severe vibration, the image point will deviate from the fiber diameter range, data transmission cannot be performed normally
