In this article, the fabrication technologies of photonic crystal fibers(PCFs) and their applications at home and abroad were formulated at length, especially in fields such as large mode-area active PCFs, fiber lasers,birefringence fibers, sensors, high nonlinear PCFs, frequency transformation, dispersion co.pensation PCFs,wideband co.munication for optical network systems, and photonic band-gap fibers. Finally, acco.ding to the above analysis, the prospects and developing trends of PCFs were presented.

作者： wei chen Shiyu li Peixiang LU wuhan National Laboratory for Optoelectronics Huazhong University of Science and Technology State Key Laboratory of optical co.munication technologies and Networks Fiberhome Telecommunication Technologies Co.Ltd.

A novelty dispersion ultra-flattened Bragg photonic crystal fiber(PCF) has been fabricated in this paper. The fiber is co.posed of co.pound co.es and periodical claddings with 11 co.xial rings. It has flattened dispersion of 8.5±1.3 ps·(nm·km)–1in the co.munication wavelength range of 1460–1625 nm. Its dispersion slope alters from – 0.0428 to 0.0392 ps·nm–2·km–1. The low attenuation of 0.52 d B/km and low bending loss of 0.09 d B at 1550 nm of the fiber are also achieved. The Bragg PCF has enormously potential application in the fields of dense wavelength division multiplexing systems because of its superior dispersion properties and easy splicing performances.

In order to increase the number of amplified azimuthal modes in Yb-doped fiber(YdF),a multiple azimuthal modes amplifier based on a ring-co.e Yb-doped fiber(rC-YdF)was proposed and demonstrated.A home-made rC-YdF which can support 6 azimuthal mode groups was employed to amplify the signal mode at 1064 nm,using a co.e pump *** amplification characteristics of 5 high-order azimuthal linear polarization(HA-LP)mode groups(LP_(11),LP_(21),LP_(31),LP_(41),LP_(51))were studied co.prehensively.A more than 8 d B gain is obtained for each signal mode with 5 d Bm input power,and the associated differential modal gain between all modes is less than 1 d *** intensity profiles of all modes are stable and well preserved during the process of amplification.
