Abstract
In order to deal with the dispersion compensation in optical fiber communication systems,a dual-core dispersion compensation photonic crystal fiber(DCPCF) was put forward.The DCPCF consists of pure silicon and air,namely that the photonic crystal fiber(PCF) is tailored by changing the radius of the first and third ring.The dispersion compensation property in PCF was simulated with the plane wave expansion method and the relation between dispersion and structural parameters was studied.Simulation results show that the dispersion of this DCPCF can reach-1956.327 ps·nm-1·km-1 and also compensate the dispersion over 100 times its length of single mode fiber.DCPCF will play an important role in optical fiber communication,especially dispersion compensation.
