An optical coupling structure, optical module and optical system

Abstract

The application provides an optical coupling structure, an optical module and an optical system. The optical coupling structure comprises a first optical transmission unit, a second optical transmission unit and an optical coupling assembly. The first optical transmission unit and the second optical transmission unit are connected through the optical coupling assembly for signal light transmission. The optical coupling assembly comprises a first lens, a photonic lead and a second lens arranged in sequence along the direction from the first optical transmission unit to the second optical transmission unit. One end of the first lens is connected with one end of the photonic lead, and the other end of the photonic lead is connected with one end of the second lens. The first lens, the photonic lead and the second lens are made of a polymer material. The first lens and the second lens are used for mode field matching between the first optical transmission unit and the second optical transmission unit. Thus, based on the combination of the lens and the photonic lead, long-distance spatial light is eliminated, light path deviation in use is reduced, and the stability of signal light transmission is improved.
