Abstract:
1. An optoelectronic integrated circuit board comprising: a substrate; a plurality of optical waveguide layers that are laminated on the substrate and that each have a core, the core being embedded by a cladding layer and having a refraction index higher than that of the cladding layer; two mirrors that are formed in each of the optical waveguide layers and that are adapted to change a light path of a light beam propagating in each core to a direction vertical and adapted to cause the light propagating directions in the cores to be opposite to each other; optical devices that are placed at positions corresponding to positions of the mirrors and that are placed on a top surface of the uppermost optical waveguide layer among the plurality of layers; and an electric wiring pattern formed on a top surface of the uppermost optical waveguide layer among the plurality of layers; wherein a portion of the electric wiring pattern is electrically connected to a portion of the optical device; and wherein transmission and reception of a light beam between the mirror in each of optical waveguide layers lower than the uppermost optical waveguide layer and the optical device are performed via a portion of a core in a layer higher than the lower optical waveguide layer.
