An optical interconnection device is provided which comprises 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.
