Abstract:
1. An optical interconnection device comprising an optical waveguide layer, wherein the waveguide layer is equipped with a plurality of electrodes which are independently drive-controllable such that a refractive index distribution is generated in the waveguide layer by drive control of the electrodes to control a propagation state of light in the waveguide layer, and an optical interconnection port is provided on an upper or lower surface or inside of the waveguide layer, and wherein the optical interconnection port is comprised of an optical element for receiving or emitting a light in a direction approximately perpendicular to a light-waveguiding surface and an optical path conversion means provided corresponding to the optical element at a given position in the waveguide layer, wherein the optical path conversion means is a light reflector with a convex shape, and the optical element is a plurality of surface elements arranged around a top of the convex of the light reflector with their centers deviated from the top of the convex such that each optical element effects emission or reception only to and from a limited region within the waveguide layer.
