Patent ID: 7271461

Claim:
An optoelectronics chip-to-chip interconnection system comprising: at least one packaged chip; at least one O-E board located in close physical proximity to the corresponding said packaged chip(s), wherein each said O-E board comprises: an E-O means for converting an outbound high-speed electrical signal from said packaged-chip to an outbound high-speed optical signal; an O-E means for converting an inbound high-speed optical signal to an inbound high-speed electrical signal for feeding to said packaged chip; and a plurality of electrical contacts for a means to transfer electrical signals, other than said high-speed electrical signals, from said packaged chip to an external printed circuit board; and a waveguide board located in close physical proximity to said O-E board, wherein said waveguide board comprises: at least one waveguide as an optical medium in said waveguide board for transmitting and receiving said high-speed optical signal, wherein each said waveguide has a beam-directing portion located at each end of said waveguide for transmitting and receiving said high-speed optical signal; and a plurality of electrical contacts for connection to external components; wherein said printed circuit board is either single-layered or multi-layered, with said waveguide board, said O-E board, and said packaged chip located on the top surface of said printed circuit board, and with low-speed electrical paths for electrical connection to external components and wherein said electrical contacts provide heat dissipation from said packaged chip to said printed circuit board.
