Abstract:
An optical waveguide member characterized in that an optical waveguide is formed at a portion over a silicon substrate, a core or a clad of the optical waveguide comprises a polymer resin, a groove in a shape of V for positioning and fixing an optical fiber to the optical waveguide and a groove extended in a direction orthogonal to the groove in the shape of V at a boundary of the optical waveguide, are provided to the silicon substrate, a film thickness of the core or the clad constituting the optical waveguide becomes thinner at a vicinity of the boundary than a film thickness of other portion and the shape of the groove having the shape of V is set such that when the optical fiber is mounted to the V-groove in the shape of V, a height of a center of a core of the optical fiber becomes a height lower than a height of a center of the core of the optical waveguide at a portion thereof at which the film thickness more remote from the boundary than the groove in the shape of V is substantially flat.
