| 1 | Silicon and hybrid silicon photonic devices for intra-datacenter applications: state of the art and perspectives [Invited]显示文摘We review the state of the art and our perspectives on silicon and hybrid silicon photonic devices for optical interconnects in datacenters. After a brief discussion of the key requirements for intra-datacenter optical interconnects, we propose a wavelength-division-multiplexing(WDM)-based optical interconnect for intra-datacenter applications. Following our proposed interconnects configuration, the bulk of the review emphasizes recent developments concerning on-chip hybrid silicon microlasers and WDM transmitters, and silicon photonic switch fabrics for intra-datacenters. For hybrid silicon microlasers and WDM transmitters, we outline the remaining challenges and key issues toward realizing low power consumption, direct modulation, and integration of multiwavelength microlaser arrays. For silicon photonic switch fabrics, we review various topologies and configurations of high-port-count N-by-N switch fabrics using Mach–Zehnder interferometers and microring resonators as switch elements, and discuss their prospects toward practical implementations with active reconfiguration.For the microring-based switch fabrics, we review recent developments of active stabilization schemes at the subsystem level. Last, we outline several large challenges and problems for silicon and hybrid silicon photonics to meet for intra-datacenter applications and propose potential solutions. | Yu Li Yu Zhang Lei Zhang Andrew W.Poon | 2015 | Photonics Research2015，3，5： | 11 |

| 3 | Predicting eczema severity beyond childhood显示文摘Background:We evaluated factors associated with eczema severity in adolescence.Methods:Nottingham Eczema Severity Score(NESS),family and personal history of atopy,skin prick test for common food and aeroallergens,highest serum IgE level and eosinophil count were evaluated.Patients with paired NESSs(childhood-NESS is NESS performed at<10 years of age;adolescence-NESS is NESS performed at age>10 years)were further analyzed.Results:Adolescence-NESS(n=383 patients)was associated with eczema onset in infancy,dust mite and food allergen sensitization,dietary avoidance,use of wet wrap,traditional Chinese medicine,immunomodulant(azathioprine or cyclosporine),high IgE level,eosinophil count,but not with family/personal history of atopy.Eighty-two patients had both childhood-NESS and adolescence-NESS(mean follow-up of 6.8 years)showing that adolescence-NESS was associated with childhood-NESS severity grades(P=0.034).Of these patients,48%remained in the same severity grades,whereas 39%improved,and 13%deteriorated from childhood to adolescence.Conclusions:It is not possible to assure parents that their child can outgrow eczema.In eczema prognosis research,long-term follow-up is warranted. | Kam Lun Hon Yin-Ching K.Tsang Terence Chuen W.Poon Nga Hin Pong Matthew Kwan Shirley Lau Yuen-Chun Chiu Hin-Hei Wong Ting-Fan Leung | 2016 | World Journal of Pediatrics2016，12，1： | 0 |
| 4 | Hybrid AlGaInAs/Si Fabry–Pérot lasers with near-total mode confinements显示文摘We have proposed and demonstrated hybrid Al Ga In As/Si Fabry–Pérot(FP) lasers, with the FP cavity facet covered by the p-electrode metal for enhancing mode confinement. Continuous-wave lasing is obtained at room temperature with a threshold current of 45 m A for the hybrid FP laser with a cavity length of 415 μm and a width of 7 μm. Near-field optical microscope images indicate an efficient output emission from the underneath evanescently-coupled silicon waveguide. Furthermore, single-mode lasing with a side-mode suppression-ratio of29 d B and a threshold current of 16 m A is realized for the 150 μm-long hybrid FP laser. | Yuede Yang Shaoshuai Sui Mingying Tang Jinlong Xiao Yun Du Andrew W.Poon Yongzhen Huang | 2018 | Journal of Semiconductors2018，39，8： | 0 |
