Abstract:
1. An optical I/O array module comprising: an optical waveguide provided on a substrate, the optical waveguide being for use in propagating a optical signal; mirror parts provided in the optical waveguide, the mirror parts each having a tapered face for varying a propagation direction of the light signal; a convex shaped member or a concave shaped member, provided above the optical waveguide, the convex shaped member or the concave shaped member being positioned at spots above the respective mirror parts; laser diode arrays and photo diode arrays, provided above the optical waveguide, the laser diode arrays and the photo diode arrays having one principal surface provided with either a concave shape, or a convex shape; a thin-film interconnect layer provided above the laser diode arrays, and the photo diode arrays, the thin-film interconnect layer being provided with electric vias; and at least one LSI of LSIs provided above the thin-film interconnect layer, the LSIs integrating circuits including a driver IC LSI, or an amplifier LSI, for either driving, or amplifying respective optical elements of the laser diode arrays and the photo diode arrays, or at least one LSI of the driver IC LSI and the amplifier LSI, wherein the laser diode array and the photo diode array each are provided with a concave shape against the convex shaped member while the laser diode array and the photo diode array each are provided with a convex shape against the concave shaped member, and the laser diode array, and the photo diode array are mated with the convex shaped member, or into the concave shaped member to effect positioning, thereby causing the laser diode array, and the photo diode array to be optically linked with the optical waveguide, and wherein a support in a convex shape, formed in the thin-film interconnect layer, is provided between a region where the laser diode arrays are disposed, and a region where the photo diode arrays are disposed, and enclosed spaces are provided within the thin-film interconnect layer, thereby electrically and optically blocking the respective laser diode arrays from the respective photo diode arrays.
