The feasibility of correlation between superconductivity and magnetic monopole: Establishment of semi-classical electrodynamics projection, TKH topological theory and dynamic vortex models

In this paper, a feasibility of semi-classical electromagnetic description together with experimental data, T-K-H topological and dynamic models and theory of vortex considered to justify the relation between superconductivity phenomena and magnetic monopole. We find that the electromagnetic energy of magnetic monopole is in agreement with vortex energy in topological theory and it can get close to thermal energy at room temperature. Indeed, these models suggest that the origin of the hot superconductivity may be magnetic monopoles with QM-Cl = 137 e (magnetic charge in classical approach) or QM-Q =137/2 e (magnetic charge in quantum approach), and the electrical conductivity is related to the mobile monopole or vortices. This research shows that the electrical permittivity ({\epsilon}) and magnetic permeability ({\mu}) of matter have a key role in the superconductive properties. We propose that this model may justify the hot superconductivity properties.Comment: 24 pages, 5 figure

Self-phase modulation-based integrated optical regeneration in chalcogenide waveguides

Copyright © 2006 IEEEWe demonstrate integrated all-optical 2R regenerators based on Kerr optical nonlinearities (subpicosecond response) in chalcogenide glass waveguides with integrated Bragg grating filters. By combining a low loss As₂S₃ rib waveguide with an in-waveguide photo-written Bragg grating filter, we realize an integrated all-optical 2R signal regenerator with the potential to process bit rates in excess of 1 Tb/s. The device operates using a combination of self phase modulation induced spectral broadening followed by a linear filter offset from the input centerwavelength.A nonlinear power transfer curve is demonstrated using 1.4 ps pulses, sufficient for suppressing noise in an amplified transmission link. We investigate the role of dispersion on the device transfer characteristics, and discuss future avenues to realizing a device capable of operation at subwatt peak power levels.Vahid G.

Chalcogenide Glasses for All-optical Processing

Copyright © 2006 IEEEChalcogenide glasses, which contain S, Se or Te atoms combined with network forming elements such as Ge, As, Sb have the largest third order optical nonlinearity of any inorganic glass. As a result they are attractive candidates for fibre and waveguide devices for all-optical signal processing in the telecommunications bands. In this talk I will review our recent progress in all-optical devices such as regenerators, wavelength converters and other devices in chalcogenide glasses.B. Luther-Davies, S. J.
