Dispersion compensation photonic crystal fibers with ultra-high dispersion coefficient and extremely low loss

摘要

We propose a dispersion compensation photonic crystal fiber (DCC-PCF) with ultra-high chromatic dispersion coefficient (D) and extremely low loss (LC). The numeric results reveal that the D≈−70790ps/km-nm and LC≈6.54×10−4dB/km at a wavelength of 1.55µm. Moreover, it is worth to emphasize that the proposed structure has an advantage of easy fabrication.
