Abstract: An opto-electric hybrid board includes an electric circuit board in which electric wiring is formed on a front surface of an insulating layer, and an optical waveguide formed on the rear side of the electric circuit board. The optical waveguide and the electric circuit board are arranged so that left and right edges of the electric circuit board along a longitudinal direction of the optical waveguide overlap with left and right edges of the optical waveguide when viewed from above, or so that the left and right edges of the electric circuit board are on the inside of where the left and right edges of the optical waveguide are located. The opto-electric hybrid board is easy to handle owing to the reduced chance of the electric circuit board being damaged. The opto-electric hybrid board also does not cause misalignment of a core when used as a connector.

Abstract: A pin hole or aperture is located or formed adjacent to the end surface of one or more of the input ports or fibers, or adjacent to one or more of the output ports or fibers, of a fiberoptic component. The aperture allows light to enter (or exit) the core of the associated fiber, and the non-transparent layer that surrounds the aperture blocks light from entering or exiting the cladding layer of the associated fiber. This blocking of the evanescent field in the cladding layer serves to reduce the polarization, wavelength, and temperature dependencies of the light coupling to the output port(s) or fiber(s) of the optical component. It can also reduce the passband width of the selected wavelength in tunable optical filter applications. The non-transparent layer surrounding the aperture can be made reflective, and light that is reflected by the non-transparent layer can be used for optical power monitoring.

Abstract: A waveguide and methods for manufacture can include a silicon wafer and a silicon substrate on the wafer that can be patterned into a silicon waveguide. A cladding can be deposited on the wafer and that waveguide using a plasma enhanced chemical vapor deposition (PECVD) process. When a PECVD process is used, the cladding portions that are in contact with that waveguide and in the immediate vicinity can have a lower density, and a lower refractive index n of less than (n<1.3). The lower uniform cladding refractive index can be uniform from the waveguide surfaces out to approximately one micrometer from the waveguide. This can further in result in an increased difference between the refractive index of the silicon waveguide and the adjacent lower refractive index cladding portions, which can further result in greater light confinement within the waveguide (i.e. reduced losses during transmission).

The ferrule has one or a plurality of holes which are parallel to the central axis at positions decentered from the central axis, the optical fiber with the lens being disposed in the hole, and the optical fibers with the lenses mounted to the pair of the ferrules have lens end faces which are inclined along the end faces of the ferrules so as to be optically coupled to each other.
