Abstract
An optical interconnect for optically coupling at least a first optical integrated circuit and a second optical integrated circuit. The optical interconnect comprises at least two layers of optically transparent material. There is a first optical waveguide arranged along a surface of a first one of the at least two layers of optically transparent material. There is further a first non-guided optical path extending from the first optical waveguide through the at least two layers of optically transparent material. A first reflective element is arranged to receive light from at least one of the first non-guided optical path and the first optical waveguide and direct the light to the other of the first non-guided optical path and the first optical waveguide. At least one lens is arranged at a boundary between two of the at least two layers of optically transparent material. The at least one lens is arranged to receive and focus light travelling along the first non-guided optical path.
