—This paper presents the latest progress toward fully embedded board-level optical interconnects in the aspect of waveguide fabrication and device integration. A one-step pattern transfer method is used to form a large cross-section multimode waveguide array with 45 micromirrors by silicon hard molding method. Optimized by a novel spin-coating surface(More)
An array of 50 ␮m ϫ 50 ␮m polymer waveguides with 45° total internal reflection ͑TIR͒ wideband coupling mirrors were fabricated by soft molding to achieve fully embedded boardlevel optoelectronic interconnects. The 45° TIR coupling mirrors were formed at the ends of the waveguides to provide surface normal light coupling between waveguides and(More)
