PURPOSE:To simplify high-accuracy optical axis alignment in optical packaging and to couple optical waveguides and optical fibers with low loss without adjustment by taking reliability and productivity into consideration. CONSTITUTION:Circular metallic pads 16 and 18 formed on the end faces of an optical waveguide element 10 and a block 21 with thin guide for aligning the optical fibers are bonded by solder bumps 17 and the optical axes of the optical waveguides 12 and V-grooves 20 are aligned with high accuracy without adjustment. Then, a block 22 with optical fiber fixing guides is adhered to the block 21 with the thin guides for aligning the optical fibers without taking care for the alignment accuracy. The high-accuracy coupling in optical packaging is easily executed simply by butting the optical fibers 14 against each other along the guides of the V-grooves 20 in the final. |
