摘　　要：WDM系统的传输速率受单模光纤 (SMF)中色散D的制约 .针对WDM系统中的色散补偿问题 ,本文提出了一种新型的用于色散补偿的双芯光子晶体光纤 (DCPCF) ,其构成材料是纯石英和空气 .采用高斯———厄密函数法计算了此DCPCF的模场和等效折射率 ,理论模拟表明这种DCPCF的色散可达 - 180 0 0ps/ (nm .km) ,并可补偿超过自身长度 10 0Chromatic dispersion (D) in single mode fibers (SMF) limits the data transmission rate in wavelength division multiplexing (WDM) systems. A novel design of dual-core dispersion compensating photonic crystal fiber (DCPCF) consisting of pure silica and air has been proposed in this letter. Simulations show that dispersion of this DCPCF can reach-18000 ps/(nm.km) and can compensate the dispersion over 1000 times its length of single mode fiber (SMF).
