PURPOSE:To improve the light condensing efficiency by providing a supporting member which bends and fixes an optical fiber and an optical waveguide which has one end closely brought into contact with the surface of the bending part of the optical fiber and has the other end formed into an exit end. CONSTITUTION:A substrate 2 used for production of an optical element is used as the means which bends an optical fiber 1 with a prescribed radius of curvature and supports it. A groove 2a formed into a desired optical fiber shape is provided on the substrate 2 with the width approximately equal to the diameter of the optical fiber 1. An optical waveguide 3 having a width approximately equal to that of the groove 2a is formed in the substrate 2. One end of the optical waveguide 3 is exposed near the apex of bend of the groove 2a, and the other is exposed to the side face of the substrate 2. Since the light radiated from the bent optical fiber 1 is very efficiently acquired, light is detected by a relatively large radius of curvature of the optical fiber 1 and a general detecting system. |
