1. an optical element coupling structure makes optical fiber and optical waveguide coupled, it is characterized in that possessing:

  • Have along the fiber cores of optical axis extending and extend to the optical fiber of fiber end face along optical axis direction;

    Have the waveguide core arranged along optical axis direction with fiber cores, towards the optical waveguide of the optical waveguide end face of above-mentioned fiber end face;

    And,Extend to optical axis direction along above-mentioned optical fiber and above-mentioned optical waveguide, have the supporting surface of support, bonding above-mentioned optical fiber, and constitute the substrate of one with above-mentioned optical waveguide,Above-mentioned supporting surface forms when above-mentioned optical fiber is in contact with it, and above-mentioned optical fiber and above-mentioned optical waveguide are arranged along optical axis direction,The refractive index of above-mentioned waveguide core is different from the refractive index of above-mentioned fiber cores,The above-mentioned relatively optical axis approximate vertical of above-mentioned fiber end face forms, and above-mentioned optical waveguide end face forms perpendicular to the face tilt of above-mentioned optical axis relatively, is provided with the gap between above-mentioned fiber end face and above-mentioned optical waveguide end face,In above-mentioned gap, fill the filling agent have with the roughly the same refractive index of the refractive index of fiber cores.
