Optical 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 کاملThree-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 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 کاملTunable transmission and bistability in left-handed band-gap structures
We study the defect-induced nonlinear transmission of a periodic structure created by alternating slabs of two materials with positive and negative refractive index. We demonstrate bistable switching and tunable nonlinear transmission in an unconventional band gap that corresponds to the vanishing average refractive index, and compare the observed effects for two different types of band gaps. ©...
متن کاملOn unusual narrow transmission bands for a multi-layered periodic structure containing left-handed materials.
Unusual narrow transmission bands are found in the Bragg reflective region of a multi-layered structure consisting of alternate right-handed material (RHM) and left-handed material (LHM). These unusual narrow transmission bands may exist no matter whether the optical length of a LHM layer completely cancels that of a RHM layer. However, if they can not cancel each other, it is required that the...
