Abstract
Opto-electrical systems having electrical and optical interconnections formed in thin layers are disclosed. In one set of preferred embodiments, optical signals are conveyed between layers by respective vertical optical couplers disposed on the layers. In other preferred embodiments, optical signals are conveyed by stack optical waveguide coupling means. Yet other preferred embodiments have electrical via means formed in one or more layers to covey electrical signals between two or more layers.
