Design on a dual-core polymer-filled photonic crystal fiber for broadband dispersion compensation

摘要

In this paper, a dual-core polymer-filled photonic crystal fiber (PCF) is designed for broadband dispersion compensation. Large negative dispersion value from -255 to -823 ps/(nm•km) over the entire C band is achieved. Furthermore, the effective refractive index of the polymer-filled outer core can be well tuned by changing the temperature. This PCF can be used for the dynamical dispersion compensation in wavelength-division-multiplexing (WDM) systems.
