| 英文摘要 | An optical fiber interface to couple a light source (1) to an optical fiber (13) and also a method of fabricating the optical fiber interface are disclosed. The optical fiber interface includes an improved optical fiber end-face which is used to couple the light power radiated from the light source to the single-mode optical fiber at high light coupling efficiency without the use of intermediate lenses. The optical fiber interface consists of a sphere (12) and part of conical surface (11) tangent to the sphere (12). In the sphere (12) the light input end-face structure of the optical fiber core (9) lies on the optical axis (Z-Z) of the optical fiber (13). The method of fabricating the optical fiber end-face in the optical fiber interface has following processes. In first process the optical fiber end-face is inserted into the ferrule and fastened there and conical surface (11) is formed by using a conventional cylindrical grinder. And in second process the conical surface (11) is pushed toward an elastic material disk whereto an abrasive material is attached so that the sphere (12) is formed by polishing the optical fiber end. |
