Non-propagating Surface Modes in Dual Singly Negative Material Layers

Abstract

We investigate the characteristics of the surface mode formed at the single interface between dual singly negative medium layers. It is shown that the interface can support a mode which has polarization degeneracy and a vanishing propagation constant. That is, this surface mode is a polarization-independent one that does not propagate at all through the interface. The corresponding electric and magnetic field distributions become static along the longitudinal (guiding) direction (but not along the transverse direction) resulting in the formation of transverse-electric/longitudinalmagnetic or transverse-magnetic/longitudinal-electric modes.

Numerical investigation of slow light in the coupled resonator optical waveguides using the local Fourier modal method

“…Since guiding mechanism of this waveguide results from the photonic bandgap, rather than the total internal reflection, it possess various interesting features such as low bending loss and small modal size. Optical resonators are also of interest due to its potential applications such as optical buffer and memory [4][5][6]. Photonic crystals with local defect result in the photonic crystal resonator [5,6].…”
