1Diagnosis of obscure gastrointestinal bleeding by intraoperative enteroscopy in 81 consecutive patients显示文摘瞄准:为了由与流血调查一系列选择病人分析 intra 起作用的肠寄生物(IOE ) 的结果和复杂并发症,怀疑了从小肠发源。方法:81 个病人(吝啬的年龄:65 年) 包括 40,男性(49.4%) 和有阴暗胃肠的流血的 41 女性(50.6%) 经历了在 1990 和 2004 之间的 IOE。病人从一个数据库被识别,数据回顾地从病人的图表被选择。所有病人在 IOE 前经历了至少一非诊断的 esophagogastroduodenoscopy,结肠镜检查,标准肠寄生物和否定腹的超声扫描。结果:在病人的中部的最小的血红素水平是 59 + 15 g/L 并且 72.8% 病人以前要求了包装红血球的输送。流血来源在 68 被检测(84%) 病人在 IOE 期间。Angiodysplasiae 在 44 个病人(54.3%) 被发现, 9 个病人(11.1%) 被溃疡在小肠影响。在小肠的一个肿瘤在另外一个被检测 6 个病人。治疗在大多数病人由 argon-plasma-coagulation,外科的缝术或有限切除术组成了。结论:Intra 起作用的肠寄生物仍然为怀疑的小肠流血的诊断被使用。最近的开发象无线的囊内视镜检查法和两倍汽球肠寄生物那样,以后可以导致 IOE 的代替。Ralf Jakobs Dirk Hartmann Claus Benz Dieter Schilling Uwe Weickert Axel Eickhoff Klaus Schoenleben Juergen F Riemann 2006World Journal of Gastroenterology2006,12,2:5
2High-performance waveguide-integrated germanium PIN photodiodes for optical communication applications[Invited]显示文摘This paper reports on high-performance waveguide-integrated germanium photodiodes for optical communications applications.200 mm wafers and production tools were used to fabricate the devices.Yields over 97%were obtained for three different compact photodiodes(10×10μm and intrinsic region width of 0.5,0.7,and 1μm)within the same batch of three wafers.Those photodiodes exhibit low dark currents under reverse bias with median values of 74,62,and 61 nA for intrinsic widths of 0.5,0.7,and 1μm,respectively,over a full wafer.Responsivities up to 0.78 A∕W at 1550 nm and zero bias were measured.Zero bias operation is possible for 25 and 40 Gbps with receiver sensitivity estimated to−13.9 and−12.3 dBm,respectively.Léopold Virot Laurent Vivien Jean-Marc Fédéli Yann Bogumilowicz Jean-Michel Hartmann Frédéric Bœuf Paul Crozat Delphine Marris-Morini Eric Cassan 2013Photonics Research2013,1,3:2
325 Gbps low-voltage hetero-structured silicongermanium waveguide pin photodetectors for monolithic on-chip nanophotonic architectures显示文摘Near-infrared germanium(Ge) photodetectors monolithically integrated on top of silicon-on-insulator substrates are universally regarded as key enablers towards chip-scale nanophotonics, with applications ranging from sensing and health monitoring to object recognition and optical communications. In this work, we report on the highdata-rate performance pin waveguide photodetectors made of a lateral hetero-structured silicon-Ge-silicon(Si-Ge-Si) junction operating under low reverse bias at 1.55 μm. The pin photodetector integration scheme considerably eases device manufacturing and is fully compatible with complementary metal-oxide-semiconductor technology. In particular, the hetero-structured Si-Ge-Si photodetectors show efficiency-bandwidth products of^9 GHz at-1 V and ~30 GHz at-3 V, with a leakage dark current as low as ~150 nA, allowing superior signal detection of high-speed data traffic. A bit-error rate of 10-9 is achieved for conventional 10 Gbps, 20 Gbps, and25 Gbps data rates, yielding optical power sensitivities of-13.85 dBm,-12.70 dBm, and-11.25 dBm, respectively. This demonstration opens up new horizons towards cost-effective Ge pin waveguide photodetectors that combine fast device operation at low voltages with standard semiconductor fabrication processes, as desired for reliable on-chip architectures in next-generation nanophotonics integrated circuits.DANIEL BENEDIKOVIC LéOPOLD VIROT GUY AUBIN FARAH AMAR BERTRAND SZELAG BAYRAM KARAKUS JEAN-MICHEL HARTMANN CARLOS ALONSO-RAMOS XAVIER LE ROUX PAUL CROZAT ERIC CASSAN DELPHINE MARRIS-MORINI CHARLES BAUDOT FRéDéRIC BOEUF JEAN-MARC FéDéLI CHRISTOPHE KOPP LAURENT VIVIEN 2019Photonics Research2019,7,4:2
