| 1 | Theoretical analysis of polarization properties for tilted fiber Bragg gratings显示文摘The polarization properties for tilted fiber Bragg gratings (TFBGs) are investigated theoretically based on coupled-mode theory and Mueller matrix method. The expression of wavelength-related polarizationdependent loss (PDL) for TFBGs with different tilt angles is derived and calculated. Simulation results are compared, and the results indicate that the polarization capability of TFBGs with 45° angle is stronger than other TFBGs with smaller angles. The degree of polarization for unpolarized light passing TFBGs is also simulated to further evaluate the polarization properties for various tilt angles. In addition, the relationship between physical parameters of a TFBG and its polarization capability is discussed. | XU OU LU ShaoHua JIAN ShuiSheng | 2010 | Science China(Information Sciences)2010，53，2： | 5 |

| 5 | Design and fabrication of erbium doped photosensitive fibers显示文摘A kind of erbium doped photosensitive fiber(EDPF) was proposed and fabricated,whose core was made of double layers named photosensitive layer and erbium doped layer.The double-layer core de-sign can overcome difficulties in fabrication of EDPF with single core design,i.e.the conflict between the high consistency rare earth doping and high consistency germanium doping.A sample was fabri-cated through the modified chemical vapor deposition method combined with solution doping tech-nique.The peak absorption coefficient was 48.80 dB/m at 1.53 μm,the background loss was lower than 0.1 dB/m,and the reflectivity of the fiber Brag gratings(FBG) written directly on the sample fiber was up to 97.3% by UV-writing technology.Moreover,a C band tunable fiber laser was fabricated using the sample fiber,in which a uniform FBG was written directly on EDPFs as a reflector.A single wavelength lasing with a maximum wavelength tuning range of 1555.2―1558.0 nm was achieved experimentally.Within this tuning range,the full-width at half maximum(FWHM) of the laser output was smaller than 0.015 nm and the side mode suppression ratio(SMSR) was better than 50 dB. | LI Jian LIU Peng LU ShaoHua WANG Jing MAO XiangQiao WEI Huai FU YongJun ZHENG Kai NING TiGang LI TangJun JIAN ShuiSheng | 2009 | Science China(Technological Sciences)2009，52，5： | 1 |

| 9 | Analysis of coupling from core mode to counter-propagating radiation modes in tilted fiber Bragg gratings显示文摘Radiation-mode coupling is stronger and more efficient in tilted fiber Bragg gratings than in other fiber gratings; it has good advantage in such fields as optical communication and optical sensors. A simplified coupled-mode theory (CMT) approach is proposed for what we believe to be the first time, whose validity is demonstrated by comparing its simulation results with that of the complete CMT equations. With the simplified CMT approach, a theoretical spectral analysis of coupling from core mode to counter-propagating radiation modes in reflective tilted fiber Bragg gratings is presented. The influence of grating length, refractive index modulation amplitude and tilt angle is exhaustively investigated on the transmission spectrum characteristics. The different dependences between s-polarized and p-polarized radiation-mode coupling on grating tilt angle are discussed, and the coupling strength of 45 -tilted gratings shows the greatest polarization dependence with the limitation of backward-propagating radiation-mode coupling. | LU ShaoHua 1,2 , XU Ou 1,2 , FENG SuChun 1,2 , DONG XiaoWei 1,2 , PEI Li 1,2 & JIAN ShuiSheng 1,2 1 Key Laboratory of All Optical Network & Advanced Telecommunication Network of EMC, Beijing Jiaotong University, Beijing 100044, China 2 Institute of Lightwave Technology, Beijing Jiaotong University, Beijing 100044, China | 2010 | Science China(Information Sciences)2010，53，5： | 1 |

| 12 | Study on pure silica core optical fibers显示文摘An optimal refractive index profile of pure silica core optical fiber (PSCF) was de- signed, in combination with the characters of the modified chemical vapor deposi- tion (MCVD) process. Techniques of preform fabrication by a new furnace round heating MCVD process and fiber drawing process were reviewed. Difficulties in doping fluorine in silica, widening the depressed-index cladding and maintaining the index of fiber core were discussed. Methods used to overcome these difficulties were given at the same time. Additionally, the optimal refractive index profiles of PSCF were presented. | LI Jian ZHENG Kai CHANG DeYuan WEI Huai NING TiGang FU YongJun MAO XiangQiao YAN FengPing JIAN Wei JIAN ShuiSheng | 2008 | Science China(Technological Sciences)2008，51，1： | 1 |
| 13 | Influences on the bandwidth at the drop port of the add/drop filter using a fiber grating coupler by uniform and linearly chirped fiber Bragg grating显示文摘Writing a fiber Bragg grating(FBG) in an optical fiber coupler is a very effective way to implement an optical add/drop filter(OADF).In order to analyze the influences on the bandwidth at the drop port of the OADF using fiber grating-assisted mismatched coupler,a uniform FBG and a linearly chirped FBG were written on the coupler,and two different OADFs were fabricated.The fiber grating is written in a 2×2 mismatched coupler,which is fused and tapered with a standard single mode fiber(SMF) and a high germanium doped photosensitive fiber,by using a 248 nm ultraviolet laser.For the OADF using the uniform FBG,the 3 dB and 20 dB bandwidths are 0.1 nm and 0.3 nm,respectively;for the OADF using the linear chirped FBG,the 3 dB and 20 dB bandwidths are 0.8 nm and 2 nm,respectively.The experimental results meet the theoretical analysis well.The bandwidth at the drop port of the device can be adjusted by adjusting the chirped coefficient of the linearly chirped FBG. | FAN LinYong JIANG WeiWei ZHAO RuiFeng LI Jian PEI Li JIAN ShuiSheng | 2013 | Science China(Information Sciences)2013，56，6： | 1 |

| 15 | Integrated liver proteomics and metabolomics identify metabolic pathways affected by pantothenic acid deficiency in Pekin ducks显示文摘Pantothenic acid deficiency(PAD)in animals causes growth depression,fasting hypoglycemia and impaired lipid and glucose metabolism.However,a systematic multi-omics analysis of effects of PAD on hepatic function has apparently not been reported.We investigated liver proteome and metabolome changes induced by PAD to explain its effects on growth and liver metabolic disorders.Pekin ducks(1-dold,n=128)were allocated into 2 groups,with 8 replicates and 8 birds per replicate.For 16 d,all ducks had ad libitum access to either a PAD or a pantothenic acid adequate(control,CON)diet,formulated by supplementing a basal diet with 0 or 8 mg pantothenic acid/kg of diet,respectively.Liver enlargement,elevated liver glycogen concentrations and decreased liver concentrations of triglyceride and unsaturated fatty acids were present in the PAD group compared to the CON group.Based on integrated liver proteomics and metabolomics,PAD mainly affected glycogen synthesis and degradation,glycolysis and gluconeogenesis,tricarboxylic acid(TCA)cycle,peroxisome proliferator-activated receptor(PPAR)signaling pathway,fatty acid beta oxidation,and oxidative phosphorylation.Selected proteins were confirmed by Western blotting.Downregulation of proteins and metabolites involved in glycogen synthesis and degradation,glycolysis and gluconeogenesis implied that these processes were impaired in PAD ducks,which could have contributed to fasting hypoglycemia,liver glycogen storage,insufficient ATP production,and growth retardation.In contrast,PAD also upregulated proteins and metabolites involved in fatty acid beta oxidation,the TCA cycle,and oxidative phosphorylation processes in the liver;presumably compensatory responses to produce ATP.We inferred that PAD decreased liver triglyceride and unsaturated fatty acids by activating fatty acid beta oxidation and impairing unsaturated fatty acid synthesis.These findings contributed to our understanding of the mechanisms of PAD-induced changes in hepatic metabolism. | Jing Tang Yongbao Wu Bo Zhang Suyun Liang Zhanbao Guo Jian Hu Zhengkui Zhou Ming Xie Shuisheng Hou | 2022 | Animal Nutrition2022，，4： | 0 |

| 17 | Optimal modulation formats for 2560 km optical transmission with low power penalty显示文摘The production mechanism of non-return-to-zero(NRZ),return-to-zero(RZ)and carrier suppressed return-to-zero(CSRZ)was analyzed theoretically in this paper.We compared the transmission performance of CSRZ with RZ and NRZ formats at 10 Gb/s system by numerical simulation.And we simulated the transmission model constructed with Erbium-doped fiber amplifier(EDFA)as the solo amplifier and the chirped fiber Bragg grating(CFBG)as the solo dispersion compensator used in the system.A practical 8x10 Gb/s 2560 km transmitted experiment was conducted in straight line with these different modulation formats mentioned above and the experiment results show very good agreement with the result of computer simulation.The CSRZ format is more effective than other formats in the system,and involved only 2.5 dB power penalty cost in the practical 2560 km error-free experiment.The results also show that CSRZ will help to optimize the transmitted results and reduce the transmitted penalty further. | CHEN Yong ZHANG Feng CAO Jihong QIN Xi LU Bo LU Dan CHEN Ming JIAN Shuisheng | 2007 | Frontiers of Electrical and Electronic Engineering in China2007，2，2： | 0 |
