Nonlinear optical systems containing a left-handed material that are studied in this paper. (a) A dispersive Kerr resonator with two layers of material: one layer consists of a right-handed medium, the other layer consists of a left-handed material. (b) A degenerate optical parametric oscillator with a left-handed material in a ring cavity. Pump and signal field are coupled by the crystal.
Marginal stability curves for several values of the detuning parameter. The hatched region contains the unstable homogeneous states. (a) . (b) . (c) .
Bistability curve relating the intensity of the input and output waves for when diffraction is negative. Full lines indicate stable homogeneous states; dashed lines indicate modulationally unstable states. Note the coexistence of stable states on the upper branch and unstable states on the lower branch.
Stable one-dimensional dissipative structure in the Kerr resonator with negative diffraction. Parameters are , , and .
Evolution of the two-dimensional emitted field. A dissipative structure seems to be formed at first, but the field finally evolves toward the stable high-intensity homogeneous state. Parameters are , , and . The first and second rows contain plots of the real and imaginary parts of , respectively.
Stripes pattern in the degenerate optical parametric oscillator with negative diffraction and positive detuning. Parameters are , , and .
