PROBLEM TO BE SOLVED: To provide an optical chip interlayer optical connector for an optical chip having multi-layer optical waveguides in which need exists to make connection for light beams from an optical waveguide in one layer to the optical waveguide in a different layer. SOLUTION: Light is coupled between a plurality of optical waveguide layers in an optical chip at a desired connection point by interconnecting the optical waveguide of each layer at the desired connection point using an "optical via". The optical via is located between the optical waveguides being connected in the layer that otherwise operates to insulate the layers containing the optical waveguides. Such an optical via may be made of a material that has an index of refraction that is conductive to optically coupling between the optical waveguides. The geometry of the interconnection at the optical via is arranged so that the light traveling in one of the optical waveguide reimages itself across the optical via and continues traveling in the other optical waveguide.
