摘要： PROBLEM TO BE SOLVED: To obtain a laminated optical waveguide which is reduced in polarization dependency of a coupling rate. SOLUTION: The laminated optical waveguide is constituted by laminating a lower clad layer 2, a lower core 21, an intermediate clad layer 4, an upper core 22, and an upper clad layer 6 on a silicon substrate 1. Then an inter-layer optical directional coupler having an optical coupling linear part 7 is composed of the upper and lower cores 21 and 22. At the optical coupling linear part 7, the cores 21 and 22 are as tall as each other, and the width of the lower core 21 is narrower than that of the upper core 22. Consequently, a similar coupling rate can be obtained whichever it is TE (transverse electric) or TM (transverse magnetic) polalization. COPYRIGHT: (C)2005,JPO&NCIPI

The optical fiber 1 is relatively moved in a first advancing direction by a cooperating motion between the X stage 8 and the ground surface 5, with the tip end of the optical fiber 1 polished by sliding it on the ground surface 5. After that, the optical fiber is inclined at a specific angle α so that the contact angle with the ground surface 5 becomes the specific contact angle θ in a second inclining direction. Then, the motion is repeated more than once in which the optical fiber 1 is relatively moved in a second advancing direction, with the tip end of the optical fiber 1 made to slide on the ground surface 5.

摘要： PROBLEM TO BE SOLVED: To suppress friction between an optical fiber and a through-hole of an optical connector when obtaining an inserting force Fi of the optical fiber. SOLUTION: An intermediate part of an optical fiber F is held with a holding tool 1 having elastic blocks 14a, 14b. If the holding tool 1 slid to an optical connector, the elastic blocks 14a, 14b provided in the holding tool 1 are elastically deformed by friction with the optical fiber F when the holding tool 1 comes to a prescribed stopping position. The optical fiber F is pressed in the inserting direction by means of the elastic force of the elastic blocks 14a, 14b. Accordingly, while the friction is suppressed with the through-hole of the optical connector caused by the distortion of the optical fiber F, the desired inserting force Fi can be obtained.
