Abstract

A system, method, and apparatus for delayed optical logic gates based on slow light and enhanced nondegenerate four-wave mixing processes, where a single or multiple delayed optical routers are utilized for dark resonance interactions in which two-color lasers interact with a three-level nonlinear optical medium comprised of two ground states and one excited state through the nondegenerate four-wave mixing processes. The delayed optical logic mechanism is based on combination of single or multiple dark resonance-induced two-photon coherence conversion via slow light phenomenon. The two-photon coherence induced on the ground states is optically detected via nondegenerate four-wave mixing processes. The nondegenerate four-wave mixing generation is enhanced owing to dark resonance or electromagnetically induced transparency. The delayed optical logic gates have potential to keep up ultra-high-bandwidth optical information processing using relatively slow electronic processing devices.

Abstract

The present invention relates to a method for preparing an organic monolith powder and an organic monolith powder prepared thereby and, more specifically, to a method for preparing an organic monolith powder, the method comprising the steps of: mixing a functional monomer and a cross-linking monomer with a solvent to prepare a mixture solution, and removing oxygen in the mixture solution (step 1); mixing the mixture solution with a pore inducing material having a molecular weight of 20,000 to 1,000,000 and a polymerization initiator, followed by a polymerization reaction (step 2); and separating organic monolith from the mixture solution in which the polymerization reaction has been conducted in step 2 (step 3). The method for preparing an organic monolith powder according to the present invention uses the pore induction material having a molecular weight of 20,000 to 1,000,000, thereby preparing an organic monolith powder which has few meso-sized pores and a large total volume of macro-sized pores. Here, the macropores are stuck into a surface region of the monolith while being absent inside the monolith pores, and thus the material transfer rate is fast, and the flow of the charging solvent is fast and strong due to the monolith form, thereby improving charging efficiency and obtaining a maximally dense charging structure. Therefore, the use of the organic monolith powder as a stationary phase of chromatography can obtain excellent separation efficiency, which is similar to that of a 5 μm-silica powder with C18 attachment.
