摘要： The lateral V-shaped groove (2) and the longitudinal V-shaped groove (3), which cross each other, are formed on a surface of the substrate (1). When the optical element (100) is contacted with and supported by four ridges composed of sides (21, 22) of one V-shaped groove and sides (31, 32) of the other V-shaped groove, the optical element is positioned at the three-dimensional support position which is geometrically determined by the four points at which the four ridges and the surface of the optical element come into contact with each other.

摘要： An optical fiber fixing member having optical fiber engagement grooves 2 and peaks 5 between the engagement grooves 2 is configured as a unitary structure by molding. A preform G is pressed with a mold 21 such that the concavities 25 of the mold 21, which comprises convexities 26 and concavities 25 for the transfer of the engagement grooves 2 and the peaks 5, respectively, are filled with the preform G only partially. The shape of the convexities 26 of the mold 21 is transferred, yielding optical fiber engagement grooves 2 whose surfaces are mold transfer surfaces 6. Because the preform G fills the concavities 25 only partially, the peaks 5 between the optical fiber engagement grooves formed by the filling of the concavities 25 are free rounded surfaces 7 whose shape does not reflect the shape of the concave bottom portions 25a of the mold 21.
