Abstract

The invention relates to a light collection coupler based on a solid light cone, which comprises a big convex end, a solid light cone and a small convex end, wherein the solid light cone forms a light receiving input end through the big convex end made by the fusion of a graphite furnace, and the small convex end made by the fusion of the graphite furnace forms a light output coupling connecting end. The light collection coupler based on the solid light cone can integrate receiving, transmitting and coupling of light signals and has the advantages of large receiving angle of field, good light transmission property, simple structure, easy manufacture and low cost. The invention is suitable for the light communication, especially for occasions, such as light beam receiving in wireless light communication, gathering of free space light, coupling between a light source and optical fibers and between light signals and the optical fibers or a photoelectric detector, and the like.

Description

technical field [0001] The invention relates to a light-collecting coupler based on a solid light cone, which is suitable for light beam reception in optical communication, free-space light collection, coupling between a light source and an optical fiber, and the like, and belongs to the field of optical communication. Background technique [0002] In the field of optical communication and optical sensing, it is usually necessary to receive light beams, including collecting spatial light, coupling light sources and optical fibers, etc., so efficient light-collecting coupling devices are particularly important. A conventional optical coupling device mainly receives and transmits an input optical signal, and then couples it into a subsequent optical receiving device. The methods used mainly include (1) guide beam. Although the field of view can be increased, the number of guide beams is large, resulting in low conversion efficiency, and it is difficult to connect with subsequ...
