Dispersion Characteristics Of Optical Waveguides Research Articles

Dispersion characteristics of optical waveguides based on ZnO nanorods

Using the method of separation of variables in the cylindrical coordinate system, the problem of propagation of electromagnetic waves in a 2D periodic lattice of ZnO nanwaveguides covered with a thin metal film is solved. Comparison of calculation results with results of simulation with the use of the COMSOL Multiphysics™ package based on the finite-element method is performed. The obtained results are used for forecasting the resonance wavelengths of a 2D periodic lattice of ZnO nanorods grown on a dielectric substrate.

Polarization corrections of dispersion characteristics of optical waveguides

The polarization corrections to optical waveguide dispersion characteristics from the scalar wave equations are calculated by an improved perturbation formula and a vector variational expression. More-accurate predictions than with the conventional first-order perturbation theory are demonstrated.
