Three-dimensional structures in nonlinear cavities containing left-handed materials.
We study the coupling between negative diffraction and direct dispersion in a nonlinear ring cavity containing slabs of Kerr nonlinear right-handed and left-handed materials. Within the mean field approximation, we show that a portion of the homogeneous response curve is affected by a three-dimensional modulational instability. We show numerically that the light distribution evolves through a s...
متن کاملOptical Bistability in Periodic Nonlinear Structures Containing Left Handed Materials
We study the transmission properties of a nonlinear periodic structure containing alternating slabs of a nonlinear right-handed material and a linear left-handed material. We find that the transmission associated with the zero-averaged refractive-index gap exhibits a bistable characteristic that is relatively insensitive to incident angles. This is in contrast to the nonlinear behavior of the u...
متن کاملNonlinear surface waves in left-handed materials.
We study both linear and nonlinear surface waves localized at the interface separating a left-handed (LH) medium (i.e., a medium with both negative dielectric permittivity and negative magnetic permeability) and a conventional [or right-handed (RH)] dielectric medium. We demonstrate that the interface can support both TE- and TM-polarized surface waves-surface polaritons, and we study their pro...
متن کاملTamm states in one dimensional photonic crystals containing left - handed materials
We present a theoretical study of electromagnetic surface waves localized at an interface separating a conventional uniform medium and a semi-infinite 1-D photonic crystal made of alternate left-handed metamaterial and right-handed material which we refer to as left-handed photonic crystal. We find novel type of surface mode’s structure, the so-called surface Tamm states and demonstrate that th...
متن کاملLosses in left-handed materials.
Interest in negative refractive index, or left-handed (LH) materials, has escalated rapidly over the last few years and it now appears that useful LH materials may be realizable in the microwave region. However there is also considerable interest in LH materials for infrared and visible applications. The purpose of this paper is to explore the limitations of LH materials at short wavelengths du...
