PROBLEM TO BE SOLVED: To miniaturize an optical module using a lens by making the angle of at least one end face of each optical fiber different from that of the end face of the other optical fiber. SOLUTION: As for this optical fiber part 10, the tip 12 of a two-core capillary 11 holding two optical fibers 13 and 14 is ground so that the angle of the tip of either optical fiber 13 may be different from that of the other optical fiber 14. By such structure, the lens need not be provided in every optical fiber and optical signals of two optical fibers are connected to other optical fiber by one lens. In such a case, as for the angle of grinding, grinding is performed so that the emitting or the incident angle of a light beam may be a desired angle, and relation between the grinding angle and the angle of the emitted light beam is decided according to the refractive index of the optical fiber and that of an incident or an emitting side Thus, the external size necessarily required in the case of assembling the optical module in a device can be miniaturized. |
