DOUBLE-SIDED TYPE AND MULTILAYER TYPE OPTICAL BACKPLANE SUBSTRATE AND FABRICATING METHOD THEREOF, IN WHICH HIGH SPEED AND LARGE VOLUME DATA IS CONNECTED OPTICALLY

摘要

PURPOSE: A double-sided type and a multilayer type optical backplane substrate and a fabricating method thereof are provided to transmit and receive optical signals of high capacity by forming the optical backplane substrate with a both-sided structure or a multilayer structure. CONSTITUTION: A plurality of clad layers(402a,402b) are formed on both sides of a substrate. A plurality of core layers(403a,403b) are patterned on each side of the clad layers. A plurality of over-clad layers(404a,404b) are formed on each side of the core layers. A plurality of metal layers are formed on each side of the over-clad layers. A waveguide is formed by laminating the clad layers, the patterned core layers, and the over-clad layers on the substrate. The clad layers, the patterned core layers, the over-clad layers are repeatedly formed on the waveguide.
