摘要： An optical fiber passive alignment apparatus for passively aligning an optical fiber with an input/output optical waveguide of an integrated optical device, and a method therefor. The optical fiber passive alignment apparatus includes: an optical waveguide formed on a planar substrate along the longitudinal direction of the planar substrate, having a core which is shorter than the planar substrate; an optical fiber mounting portion formed to a predetermined length on the planar substrate in the longitudinal direction of the planar substrate, such that the optical waveguide and the optical fiber contact each other, for receiving the optical fiber; and a cavity located between the optical fiber mounting portion and a core of the optical waveguide, filled with a material whose refractive index slightly increases on irradiation by UV rays such that the refractive index of the material is not substantially different from the refractive index of a core of the optical fiber. Therefore, forming the optical waveguide whose core flares gradually reduces dependency of coupling loss on horizontal displacement, and importance of precisely positioning the optical fiber is decreased.

摘要： An optical waveguide chip includes an output waveguide connected to an optical fiber, an optical fiber array module, or another optical waveguide chip. The output waveguide has a coupling cross-section wider than the core of the optical fiber, the core of an optical fiber of the optical fiber array module, and the waveguide of the other optical waveguide, respectively. The cross-section width of the output waveguide of the optical waveguide chip gradually increases toward an end of the waveguide with a slant angle of 10° or less. Therefore, when the optical waveguide chip is connected to the optical fiber, the optical fiber array module, or the other optical waveguide chip during packaging of an optical waveguide device, an offset of the optical axis of about ±20% of the width of the waveguide guide is allowable. As a result, there are no additional or extra steps in fabrication of an optical waveguide chip and no additional loss of the optical characteristics, and the required interconnection or production time is considerably reduced.

摘要： A metal coated optical fiber array module including a metal coated optical fiber array, an arranging substrate having arranging grooves for loading the optical fiber array, wherein a metal is coated on the upper surface including the arranging grooves and the optical fiber array loaded into the arranging grooves is united therewith through the medium of the metal, and a cover for protecting and fixing the optical fiber array loaded into the arranging grooves of the arranging substrate. It is preferable that the optical fiber array module further includes a planar substrate having holes into which the optical fiber array is to be inserted, wherein the optical fiber array loaded on the arranging substrate is inserted into the holes and united with the arranging substrate. After the optical fibers are loaded, the ends thereof are easily polished. When the optical fibers are attached to a waveguide device, the ends of the arrayed optical fibers are enlarged to increase an attachment strength at the contact surface. The axes of the optical fibers are prevented from being tilted, by ultraviolet (UV) irradiation upon loading the optical fibers. Also, when the optical waveguide device is attached to a multi-core optical fiber, a contact surface is widened, thus improving environmental characteristics and reliability of a device package upon connection of the optical fibers.
