|Title||Negative Refractive Index – Semiconductor Circular Waveguide Fiber|
In this work, we will consider the electromagnetic waves propagation along the symmetric cylindrical fiber with left handed material (LHM) as the core layer bounded by a semiconductor clad layer. We will study the dispersion properties in the considered optical fiber for two cases. In the first case, we consider the leading diagonal elements of the semiconductor permittivity tensor are different from each other. In the second case , we consider as a special case, the elements are equal to each other. In the two cases, the fast and slow modes will be studied in TE, TM, HE and EH mode polarizations. The dispersion relations for all modes will be obtained from Maxwell's equations. The total power flow in the structure within core and clad layers will be calculated in the general and in special cases for TE and TM mode polarizations. The dispersion curves for TE, TM, HE and EH modes will be studied for different parameters of the structure.
