摘要： A prism pair is employed as an optical deflecting element. The prism pair is constructed by a slab waveguide, and first and second upper electrodes and first and second lower electrodes arranged on and under the slab waveguide. These electrodes are shaped into a wedge shape (e.g., triangular shape), and change the refractive index of a part of the slab waveguide by utilizing the electrooptic effect to change the propagation direction of light.

摘要： An optical waveguide structure capable of optically coupling a surface type optical device, such as a surface emitting laser diode or a photodiode, and a transmission medium, such as an optical fiber, located so that their light output surface and light input surface will form an angle of about 90° with each other simply and easily. The optical waveguide structure comprises a first clad section having a curved surface for gradually turning the direction in which light travels almost squarely and a groove formed in the curved surface along the direction in which light travels, a core section which is made from a transparent material with a refractive index higher than the refractive index of the first clad section and with which the groove is filled in, and a second clad section which covers an exposed surface of the core section and the curved surface of the first clad section and which is integrated with the first clad section.

摘要： An optical waveguide and a first lens are formed on an underlying surface. The optical waveguide guides light along a first direction. The first lens is continuous with one end of the waveguide and converges light radiated from the end plane of the optical waveguide and diverging along directions parallel to the underlying surface. A second lens converges light transmitted through the first lens and diverging along directions perpendicular to the underlying surface. A support member supports the first and second lenses. It is possible to prevent a shift of positions of the optical waveguide and lens to be caused by a temperature change and to prevent a light coupling efficiency from being lowered.

摘要： An optoelectronic component is mounted at a precise position on a waveguide substrate so as to reduce loss in propagating light, and electrically connect electrodes on the waveguide substrate and the optoelectronic component. The waveguide substrate has an optical waveguide and a recessed portion for mounting the optoelectronic component, and electrodes are arranged on the recessed portion. A great number of globular elastic conductive particles are distributed on the bottom surface of the recessed portion. Thereafter, the optoelectronic component is placed in the recessed portion so as to press the globular elastic conductive particles, and alignment between the optical waveguide in the waveguide substrate and an optical waveguide in the optoelectronic component is adjusted. Then, the optoelectronic component is fixed to the waveguide substrate with an optical adhesive while the alignment is precisely adjusted.

摘要： A circuit substrate comprises a glass substrate 16, through-holes 18 formed through the glass substrate 16 and via electrodes 20 buried in the through-holes 18. An opening width of the through-holes 18 is minimum inside the glass substrate and is increased toward both surfaces of the glass substrate 16. Accordingly, the detachment of the via electrodes 20 can be prevented without increasing the surface roughness of the inside walls of the through holes, and stresses generated in the core substrate can be mitigated.
