摘要：We report the des.gn and fabrication of a novel and fully integrated polymer-bas.d centrifugal microfluidic dis. for rapid automatic allergens.detection. All es.ential s.eps.for a s.ngle tes. including flow valving, s.quencing, mixing, s.paration, extraction, and s.dimentation for final detection are automatically conducted within 30 min on a centrifugal microfluidic dis.. Our des.gn features.a s.phon-bas.d valving and analyte extraction s.ructure where the releas.d analyte is.s.parated and s.bs.quently extracted by a s.phon valve into the detection chamber. Incorporating the s.phon valve and a s.ries.of capillary valves. we realize automated detection of allergic reaction on a centrifugal microfluidic dis..

摘要：声光可调滤光器（ＡＯＴＦ）具有独特的光波长调谐功能，可望用于光通信的波分复用（ＷＤＭ）技术。而共束声光滤光器（ＣＢ－ＡＯＴＦ）兼顾了共线和非共线ＡＯＴＦ的优点。给出ＣＢ－ＡＯＴＦ的工作原理和设计方法。获得了在２０ｍＷ下９８％的衍射效率，旁瓣抑制优于３３ｄＢ和线宽０．８ｎｍ的结果。
