提出了一种用于宽带高速传输系统的新型色散补偿光子晶体光纤。利用有限差分法和各向异性完全匹配吸收层边界条件研究了波导的导频特性。设计的新型DC-PCF表明，通过使用适当的设计参数，可以在整个S+C+L通信频段获得更大的负色散系数，更好的色散斜率补偿和小于10−4dB/m的限制损耗。该模块可应用于40 Gb/s密集波分复用（DWDM）光纤通信系统中。
This paper reveals a novel dispersion compensating photonic crystal fiber (DC-PCF) for wide-band high-speed transmission systems. The finite-difference method with an anisotropic perfectly matched absorbing layers boundary condition is used to investigate the guiding properties. The designed novel DC-PCF shows that it is possible to obtain a larger negative dispersion coefficient, better dispersion slope compensation, and confinement losses less than 10−4dB/m in the entire S+C+L telecommunication band by using a modest number of design parameters. The proposed module can be used in 40Gb/s dense wavelength division multiplexing (DWDM) systems in optical fiber communication networks.
