OPTICAL WAVEGUIDE AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To reduce the transmission loss and manufacturing time of a self-formed optical waveguide. SOLUTION: The end face 21 of the core of an optical fiber 2 is introduced into a case 1 composed of a transparent resin and is fixed by a fixing member 3. A wavelength selective mirror 4 is fixed on the bottom face of the case 1 being tilted by 45 degree with respect to the bottom face. The case 1 is filled with an unhardened photosetting resin liquid 5 (1.A). A hardened material 5c is formed into an axial shape having branches along the optical path of light when the photosetting resin liquid 5 filled in the case 1 is irradiated with the light having a photosetting wavelength from the end face 21 (1.B). Then the unhardened photosetting resin liquid 5 is removed and the inside of the the case is plated with a metal. The inside of the case 1 is filled with an unhardened setting resin liquid 6 which is to become a supporting member. The setting resin liquid 6 is hardened to become a hard material 6c, and an optical wave guide having a core of the plated hardened material 5c is formed (1.D). An optical module 100 in which a single line bidirectional communication is performed is completed by mounting a light receiving element 7 and a light receiving element 8 (1.E).
