摘要： Method for producing a lens array, which can prevent a weld from being formed in the peripheral part of a lens part and suppress increase of a work time of a transfer mold, and a molding mold. Since a master mold 10 of a molding mold has a plurality of linear groove parts 14e surrounding a plurality of cavity parts 12, resin hardly spreads to a corner part 14p where the adjacent linear groove parts 14e and 14e intersect each other and it is possible to prevent portions of the resin which have run over toward the adjacent groove parts 14e and 14e from spreading so as to come close to each other and being brought into contact with each other to create a weld trapping air bubbles.

摘要： An optical fiber coupling member and a manufacturing method thereof are provided for reducing a decrease in the coupling efficiency upon coupling of a multi-core fiber with a fiber bundle. A coupling member includes one end in contact with a first optical waveguide that includes a bundle of single cores each covered with a cladding, another end in contact with a second optical waveguide that includes a plurality of cores each covered with a cladding, and a predetermined medium that fills between the one end and the other end. The optical fiber coupling member changes the mode field diameter of each of light rays incident from each optical path of the first optical waveguide. The optical fiber coupling member changes the intervals of the light rays, the mode field diameter of which has been changed, and guides the light rays to the cores of the second optical waveguide.
