Coherent detection employing multilevel modulation formats has become one of the most promising technologies for next generation high speed transmission systems due to the high power and spectral efficiencies. Using the powerful digital signal processing (DSP), coherent optical receivers allow the significant equalization of chromatic dispersion (CD), polarization mode dispersion (PMD), phase n...

The paper addresses optical solitons in magneto-optic waveguides that are studied using Kudryashov’s law of nonlinear refractive index the presence chromatic dispersion and Hamiltonian-type perturbation terms. trial solution approach yielded a variety soliton solutions, which listed this paper.

A highly nonlinear photonic crystal fiber with eight ring octagonal structure is proposed. Chalcogenide glass of As2S3 is used as the material for this photonic crystal fiber structure. The finiteelement method with perfectly matched boundary layer is employed to analyze the guiding properties. Non linearity of 13,584.5 per W-km is obtained at 1.55 μm with reasonable flattened dispersion of -25...
