Paper Abstract

In this paper, we calculated the propagation constant β, the group velocity, the group velocity dispersion, and the optical field distribution in straight or curved nanometer-waveguide by means of the scale FDTD method. From the calculated results, we can find that the curve of nanometer-waveguide has influence on the dispersion of the waveguide, when the radius of nanometer-waveguide is smaller, the influence is larger. The evolutions of group velocity vg and group velocity dispersion Dw obtained by us are different from the results obtained in other papers. And the field distribution of curved waiveguide slopes towards the outside of the bend radius, smaller the bend radius is, the larger the slope of the field distribution is.
