| 1 | Generating optical orbital angular momentum at visible wavelengths using a plasmonic metasurface显示文摘Light beams with a helical phase-front possess orbital angular momentum along their direction of propagation in addition to the spin angular momentum that describes their polarisation.Until recently,it was thought that these two‘rotational’motions of light were largely independent and could not be coupled during light–matter interactions.However,it is now known that interactions with carefully designed complex media can result in spin-to-orbit coupling,where a change of the spin angular momentum will modify the orbital angular momentum and vice versa.In this work,we propose and demonstrate that the birefringence of plasmonic nanostructures can be wielded to transform circularly polarised light into light carrying orbital angular momentum.A device operating at visible wavelengths is designed from a space-variant array of subwavelength plasmonic nano-antennas.Experiment confirms that circularly polarised light transmitted through the device is imbued with orbital angular momentum of 62'(with conversion efficiency of at least 1%).This technology paves the way towards ultrathin orbital angular momentum generators that could be integrated into applications for spectroscopy,nanoscale sensing and classical or quantum communications using integrated photonic devices. | Ebrahim Karimi Sebastian A Schulz Israel De Leon Hammam Qassim Jeremy Upham Robert W Boyd | 2014 | Light(Science & Applications)2014，3，1： | 39 |
| 2 | 抗炎介质表达缺陷参与中性粒细胞型支气管哮喘发病机制:半乳糖凝集素-3和白细胞介素-1RA/白细胞介素-1beta比例显著下降显示文摘支气管哮喘(哮喘)是具有异质性的气道炎症性疾病,其主要特点表现为气道高反应和可变的气流受限。在哮喘的发病机制中,过敏原诱导的TH2淋巴细胞激活以及IL-5介导的嗜酸粒细胞渗出起到重要的作用。近年来发现超过50%的哮喘患者气道的嗜酸粒细胞水平并不增高,并将这种亚型定义为非嗜酸粒细胞型哮喘。其中部分患者表现为气道中性粒细胞明显增高,称为中性粒细胞型哮喘。 | 高鹏 Peter G Gibson Katherine J Baines Ian A Yang John W Upham Paul N Reynolds Sandra Hodge Alan L James Christine Jenkins Matthew J Peters 张捷 Jodie L Simpson | 2016 | 中华结核和呼吸杂志2016，39，11： | 5 |
