| 8 | Comparative effectiveness of i-SCAN^(TM) and high-definition white light characterizing small colonic polyps显示文摘AIM:To evaluate accuracy of in vivo diagnosis of adenomatous vs non-adenomatous polyps using i-SCAN digital chromoendoscopy compared with high-definition white light.METHODS:This is a single-center comparative effectiveness pilot study.Polyps(n = 103) from 75 averagerisk adult outpatients undergoing screening or surveillance colonoscopy between December 1,2010 and April 1,2011 were evaluated by two participating endoscopists in an academic outpatient endoscopy center.Polyps were evaluated both with high-definition white light and with i-SCAN to make an in vivo prediction of adenomatous vs non-adenomatous pathology.We determined diagnostic characteristics of i-SCAN and highdefinition white light,including sensitivity,specificity,and accuracy,with regards to identifying adenomatous vs non-adenomatous polyps.Histopathologic diagnosis was the gold standard comparison.RESULTS:One hundred and three small polyps,detected from forty-three patients,were included in the analysis.The average size of the polyps evaluated in the analysis was 3.7 mm(SD 1.3 mm,range 2 mm to 8 mm).Formal histopathology revealed that 54/103(52.4%) were adenomas,26/103(25.2%) were hyperplastic,and 23/103(22.3%) were other diagnoses include 'lymphoid aggregates','non-specific colitis,' and 'no pathologic diagnosis.' Overall,the combined accuracy of endoscopists for predicting adenomas was identical between i-SCAN(71.8%,95%CI:62.1%-80.3%) and high-definition white light(71.8%,95%CI:62.1%-80.3%).However,the accuracy of each endoscopist differed substantially,where endoscopist A demonstrated 63.0% overall accuracy(95%CI:50.9%-74.0%) as compared with endoscopist B demonstrating 93.3% overall accuracy(95%CI:77.9%-99.2%),irrespective of imaging modality.Neither endoscopist demonstrated a significant learning effect with i-SCAN during the study.Though endoscopist A increased accuracy using i-SCAN from 59%(95%CI:42.1%-74.4%) in the first half to 67.6%(95%CI:49.5%-82.6%) in the second half,and endoscopist B decreased accuracy using i-SCAN from 100%(95%CI:80.5%-100.0%) in the first half to 84.6%(95%CI:54.6%-98.1%) in the second half,neither of these differences were statistically significant.CONCLUSION:i-SCAN and high-definition white light had similar efficacy predicting polyp histology.Endoscopist training likely plays a critical role in diagnostic test characteristics and deserves further study. | Johanna L Chan Li Lin Michael Feiler Andrew I Wolf Diana M Cardona Ziad F Gellad | 2012 | World Journal of Gastroenterology2012，18，41： | 3 |

| 11 | High-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 | 2013 | Photonics Research2013，1，3： | 2 |
| 12 | 25 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 | 2019 | Photonics Research2019，7，4： | 2 |
