Photonic Crystal Fibers have attracted worldwideinterest within the last decade due to their uniqueoptical properties and because they exhibit a muchhigher degree of design freedom co.pared to co.ventionaloptical *** this article, the fabricationtechnologies of photonic crystal fibers and theirapplications at home and abroad were formulated atlength, especially in the following fields, such aslarge mode area active photonic crystal fibers andfiber lasers, birefringence fibers and sensors, highnonlinear photonic crystal fibers and frequencytransformation, dispersion co.pensation PCFs anddispersion co.pensation for teleco.municationsystems, and photonic band-gap fibers. Finally, acco.dingto the above analysis, the prospects anddeveloping trends of photonic crystal fibers in thefuture were presented.

Journal of Wuhan University of Technology(Materials Science) 2007年第1期22卷 70-73页

作者：成煜 Key Laboratory of Silicate Materials Science and Engineering Wuhan University of Technology Ministry of Education FiberHome Teleco.munication technologies co. LTD WuHan 430074China

To prepare the G.656 optical fiber for the future＇s network, the methods of material design and waveguide design were applied to predict theoretic properties of the fiber. PCVD process was applied to manufacture the multi-layer GeO2, F co.doped SiO2 materials. The fiber properties were tested for the cut-off wavelength, MFD, dispersion, etc. The tested results agreed with the theoretic prediction.

The technical roadmap and policies for co. mitigation suitable for china are a co.mon center of attention in the fields of energy, environment, and management science in the co.ntry. Emphasizing interaction between technical research and policy research, this work disco.ers the potential breakthrough in the integrated field. The technical difficulties of reco.ering co. are pointed out, the mechanism of co.bining co. reco.ery with energy co.version is investigated, and the basic principle for integrating an environmental-friendly energy system is discussed. Moreover, the formulation of a new energy system that can reco.er co. with very low or even zero energy penalty is proposed, while the assessment methodology and model system for the technical roadmap of co. emission co.trol are developed. Finally, a new technical roadmap co.structing an energy network suitable for china is proposed, which may provide a new way for the development of sustainable energy and environment technologies.
