    摘要: Provided is an optical component for optical communication which is capable of suitably accepting a request to reduce a size, resisting a thermal expansion coefficient difference between constituent elements, and adjusting incident and exit modes relative to an end of an optical fiber to thereby constantly attain optical characteristics which correspond to the request. The optical component includes a fiber holding member (3) holding an optical fiber (2), and a lens (4) which is located on an optical path extending from an end of the optical fiber (2) and attached to the fiber holding member (3). A flat portion (4a) formed in a rear end of the lens (4) is bonded to be fixed to a flat portion (6a) of an end of the fiber holding member (3) such that the flat portion (4a) of the lens (4) is opposed to the end of the optical fiber (2). A gap is provided between the flat portion (4a) of the lens (4) and the end (2a) of the optical fiber (2).

    摘要: In the capillary tube 22, the cross section of the outer surface is substantially square, and the cross section of the insertion hole 23 is substantially square. Sides La, Lb of the outer surface have high dimensional accuracy and the insertion hole 23 is made to allow two optical fibers 5, 6 to be inserted while adjoining each other and arranged in order therein. The phases of the outer surface and the insertion hole 23 are relatively offset with each other, so that angles &thgr;a, &thgr;b which the sides 23a, 23b of the insertion hole 23 form with flat surfaces 22a, 22b of the outer surface are acute angles of substantially 45°±0.5°. Consequently, the flat surface 22a becomes substantially parallel to the center line M that connects the centers of the cores 5a, 6a of the two optical fibers 5, 6 inserted in the insertion hole 23, and the flat surface 22b becomes substantially perpendicular to the center line M.

    摘要: Provided are a method for manufacturing a liquid crystal lens which, even with the use of a thin sheet glass as a glass sheet for dividing a liquid crystal layer, can reduce the likelihood of breakage of the thin sheet glass in the production process and the liquid crystal lens. A mother liquid crystal lens having a plurality of liquid crystal lens units arrayed in a longitudinal direction thereof is cut for each of the liquid crystal lens units to separate out the liquid crystal lens units and thus manufacture respective liquid crystal lenses 10. Longitudinally extending side surfaces 13c, 13d, 14c, and 14d of glass ribbons which provide thin sheet glasses 13 and 14 have an outwardly bulging curved shape in a cross section perpendicular to the longitudinal direction.

    摘要: The present invention can further increase the efficiency of light extraction from the light exit surface of a light-emitting device. A cell (10) for a light-emitting device includes: a first main wall (10a) and a second main wall (10b) which are disposed facing each other with a distance therebetween; and a sidewall (10c). The sidewall (10c) connects the first main wall (10a) and the second main wall (10b). The sidewall (10c) defines, together with the first and second main walls (10a, 10b), an internal space (10A) into which a luminescent substance is to be encapsulated. A portion of the sidewall (10c) located laterally of the internal space (10A) is white.
