摘要： An apparatus for aligning an optical waveguide device has functional waveguides for transmitting signal light and internal and external waveguides, located on the periphery of the functional waveguides, with optical fiber blocks and includes an optical source, a first optical fiber block having a plurality of first functional optical fibers each connected to one end of each of the functional waveguides, and a plurality of first alignment optical fibers each aligned with one end of each of the internal and external waveguides for transmitting light generated by the optical source, a second optical fiber block having a plurality of second functional optical fibers each connected to the other end of each of the functional waveguides, and a plurality of second alignment optical fibers each aligned with the other end of each of the internal and external waveguides, a measuring unit for measuring an intensity of light output from the second alignment optical fibers, and a controller for receiving the intensity of light from the measuring unit and finely adjusting the alignment of the first optical fiber block with the optical waveguide device and the optical waveguide device with the second optical fiber block in order to maximize the received intensity of light. A waveguide-type optical device can be aligned with optical fiber blocks regardless of the wavelength, by using input and output alignment optical fibers and internal and external bending waveguides in the optical device. Therefore, there is no need to know accurately the wavelength properties of an individual device.

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.
