A new circular chalcogenide/silica hybrid microstructured optical fiber with high negative dispersion for the purpose of dispersion compensation

In this paper, a new circular microstructured optical fiber (C-MOF) based upon photonic band gap (PBG) light guiding mechanism is proposed which can be used for dispersion compensation in optical transmission systems. The C-MOF core is made up of silica glass and the holes in the cladding network are filled with As2Se3 chalcogenide glass. By selecting an appropriate geometrical parameters for the structure, the dispersion and confinement losses of the proposed C-MOF at 1.55 μm are respectively calculated to be −2450 ps/nm/km and 0.013 dB/m. Relative dispersion slope (RDS) of the C-MOF at 1.55 μm is about 0.00332 nm−1. The proposed C-MOF is suitable for use in wavelength division multiplexing and dispersion compensating systems in optical fiber transmission networks.
