Tailoring of nearly zero flattened dispersion photonic crystal fibers

This work theoretically tailored the dispersion in a photonic crystal fiber (PCF), and then designed two types of nearly zero dispersion flattened PCFs (DFPCFs) by rod-doping or liquid-filling some of the cladding holes.

Description
Summary:This work theoretically tailored the dispersion in a photonic crystal fiber (PCF), and then designed two types of nearly zero dispersion flattened PCFs (DFPCFs) by rod-doping or liquid-filling some of the cladding holes. The numeric results show that the DFPCF type 1, rod-doped with arbitrary indices, achieves the dispersion values between 0±1ps/nmkm over a bandwidth range of 460nm. The DFPCF type 2, filled with the available liquids, performs the dispersion values between 0±1.5ps/nmkm over a bandwidth range of 520nm. Finally, the confinement losses of the two types of DFPCFs are estimated. The numeric results show that the confinement losses of the two types of the proposed DFPCFs are extremely low, in the order of 10−5 or 10−6dB/km, which even can be disregarded. •Two types of DFPCFs are investigated.•I tailored the waveguide dispersion to nullify the material dispersion.•The tailor tendencies of DG(λ) curves were developed firstly to tailor the DG.•The chromatic dispersions are nearly zero within a broadband of wavelength.•The confinement losses are extremely low that even can be disregarded.
