1Femtojoule electro-optic modulation using a silicon– organic hybrid device显示文摘Energy-efficient electro-optic modulators are at the heart of short-reach optical interconnects,and silicon photonics is considered the leading technology for realizing such devices.However,the performance of all-silicon devices is limited by intrinsic material properties.In particular,the absence of linear electro-optic effects in silicon renders the integration of energy-efficient photonic–electronic interfaces challenging.Silicon–organic hybrid(SOH)integration can overcome these limitations by combining nanophotonic silicon waveguides with organic cladding materials,thereby offering the prospect of designing optical properties by molecular engineering.In this paper,we demonstrate an SOH Mach–Zehnder modulator with unprecedented efficiency:the 1-mm-long device consumes only 0.7 fJ bit^(-1) to generate a 12.5 Gbit s^(-1) data stream with a bit-error ratio below the threshold for hard-decision forward-error correction.This power consumption represents the lowest value demonstrated for a non-resonant Mach–Zehnder modulator in any material system.It is enabled by a novel class of organic electro-optic materials that are designed for high chromophore density and enhanced molecular orientation.The device features an electro-optic coefficient of r33<180 pm V^(-1) and can be operated at data rates of up to 40 Gbit s^(-1).Sebastian Koeber Robert Palmer Matthias Lauermann Wolfgang Heni Delwin L Elder Dietmar Korn Markus Woessner Luca Alloatti Swen Koenig Philipp C Schindler Hui Yu Wim Bogaerts Larry R Dalton Wolfgang Freude Juerg Leuthold Christian Koos 2015Light(Science & Applications)2015,4,1:4
2抗生素骨水泥髋臼顶可增强人工髋关节感染翻修骨水泥占位器的稳定性显示文摘人工髋关节感染的二期翻修间隔期,骨水泥占位器脱位、碎裂是常见的临床问题。作者应用抗生素骨水泥髋臼顶增强骨水泥占位器的稳定性,分析了47例患者(50髋)资料。发现术后无占位器脱位、碎裂和其它与抗生素骨水泥髋臼顶相关并发症。13例(26%)使用占位器超过120 d,7例翻修术后感染复发。因此认为,可以采用抗生素骨水泥髋臼顶增强人工髋关节感染翻修骨水泥占位器的稳定性。Drexler Kuzyk P R Koo K 胡孔足 2016临床骨科杂志2016,19,3:2
