Optical guided waves at graded metal–dielectric interfaces

Not Accessible

Your library or personal account may give you access

Abstract

Waveguides at interfaces with a linearly graded permittivity between a metal and a dielectric are studied. Analytic expressions for the dispersion relations, modes, losses, and cutoff wavelengths are derived and agree well with simulations. The gradation results in anomalous dispersion, a reduction in the energy velocity, and increased field confinement in the metal–dielectric transition region. These effects lead to increased propagation losses, which are sensitive to the spatial extent of the interface gradation.
