Photosynthesis is used by plants, algae and bacteria to convert solar energy into stable chemical energy. The initial stages of this process--where light is absorbed and energy and electrons are transferred--are mediated by reaction centres composed of chlorophyll and carotenoid complexes. It has been previously shown that single small molecules can be used… (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)
We present a method that uses text mining methods and statistical distributions to infer degrees of collaboration between staff members in an organization, based on the similarity of the documents that that they wrote and exchanged over time.
—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)
