Hyperbolic transverse patterns in nonlinear optical resonators.
We consider a nonlinear optical system in general, and a broad aperture laser, in particular, in a resonator where the diffraction coefficients are of opposite signs along two transverse directions. The system is described by the hyperbolic Maxwell-Bloch equations, where the spatial coupling is provided by the D'Alambert operator rather than by the Laplace operator. We show that this system sup...
متن کاملOptical absorption of hyperbolic metamaterial with stochastic surfaces.
We investigate the absorption properties of planar hyperbolic metamaterials (HMMs) consisting of metal-dielectric multilayers, which support propagating plane waves with anomalously large wavevectors and high photonic-density-of-states over a broad bandwidth. An interface formed by depositing indium-tin-oxide nanoparticles on an HMM surface scatters light into the high-k propagating modes of th...
متن کاملBroadband Acoustic Hyperbolic Metamaterial.
In this Letter, we report on the design and experimental characterization of a broadband acoustic hyperbolic metamaterial. The proposed metamaterial consists of multiple arrays of clamped thin plates facing the y direction and is shown to yield opposite signs of effective density in the x and y directions below a certain cutoff frequency, therefore, yielding a hyperbolic dispersion. Partial foc...
متن کاملSub-Diffraction Light Structures in Optical Parametric Oscillators
Previously, we have proposed a method of diffraction management in optical resonators with left-handed materials. This method is now applied to parametric oscillators. We show that it is possible to engineer the sign and strength of diffraction for either the pump or signal beam – not both. We study the influence of the altered diffraction on the periodic structures and phase solitons emerging ...
متن کاملProperties of sub-diffraction limited focusing by optical phase conjugation.
Recent work has demonstrated sub-diffraction limited focusing using time-reversal mirrors and sources in scattering media at microwave frequencies. We numerically investigate the possibility of observing analogous effects in the optical domain using small cylindrical scatterers of realistic dielectric materials combined with an enclosing optical phase conjugate mirror in two-dimensional geometr...
