According to Maxwell equations and boundary conditions of electromagnetic field,the general dispersion equations are reduced for the guided modes in rectangular dielectric waveguides.

The results show that the number of possible guided modes in such a waveguide depends on the peak intensity of the soliton.

In line with the symmetry analysis of modes in a waveguide, we classify guided modes in the elliptical core photonic crystal fibers (PCFs) according to the minimum waveguide sectors and their appropriate boundary conditions with a full vector model.

In this paper we calculate the guided modes in SIE region of the MMI optical splitter by numerical calculation.

Negative effective refraction index in guided wave mode for periodic layered ferrite-dielectric/metallic film composites;

We have investigated the guide modes in two kinds of two_dimensional photonic crystal heterostructures by using the plane wave expansion method combined with the supercell technique.
