光子晶体光纤的原理、结构、制作及潜在应用

传统光纤中的光能损耗和色散是阻碍其进一步向大容量和远距离通信方向发展的主要原因，因此制造具有低色散和低损耗的光子晶体光纤成为光纤技术努力的方向。在介绍光子晶体光纤的制作、导光原理和特点的基础上，研究了普通光纤不具备，而光子晶体光纤所具有的无休止的单模特性、奇异的色散特性、可控的非线性和易于实现的多芯传输等特点。研究结果表明，光子晶体光纤在光纤传感器、光子晶体天线、超宽色散补偿、光学集成电路等多方面具有广泛的应用前景。

Principle, configuration, manufacture and potential application of photonic crystal fiber

The main reason that blocks traditional fiber to develop towards big capacity and long distance communication is the loss of light energy and dispersion,so the manufacture of photonic crystal fiber with lower loss and dispersion will be the direction of fiber development.Based on the introduction of the manufacture,principle and characteristics of photonic crystal fiber,and comparison with the common fiber,the characteristics of "endless" single-mode,strange dispersion,controllable nonlinear and more cores' transmission of the photonic crystal fiber are investigated.The result shows that the photonic crystal fiber will have a broad application in photonic crystal fiber sensor,photonic crystal antennae,dispersion compensation and optical integrated circuit.
