Photonic metamaterials

Laser Physics Letters, 2008
The invention of metamaterials prompts reconsideration of a number of fundamental physical phenomena and enables a variety of unique properties and functionalities. These include negative refractive index, magnetism at optical frequencies, sub-wavelength resolution, ``backward'' phase matching conditions for nonlinear optical processes, and even ...

Dyakonov Surface Waves in Photonic Metamaterials

Physical Review Letters, 2005
We show that suitable photonic metamaterial structures can support lossless surface waves of the form envisaged by Dyakonov. The idea we put forward is based on the birefringent properties of photonic crystals in the long-wavelength limit, and uses the metamaterial anisotropy of the structures to meet the resonance conditions at which Dyakonov surface ...

Tunable photonic metamaterials

Journal of Modern Optics, 2009
We illustrate a mechanism based on coherent optical nonlinearities to realize optically tunable photonic crystals built from media supporting electromagnetically induced transparency. These exhibit specific periodic patterns where a light probe can experience a fully developed photonic band-gap with negligible absorption.

Dielectric photonic metamaterials

2013 15th International Conference on Transparent Optical Networks (ICTON), 2013
Magnetic resonances can be achieved at visible and near-infrared frequencies in purely dielectric metamaterials via the coupling between pairs of closely spaced, dissimilar dielectric rods. We demonstrate this new phenomenon experimentally and explore how such structures may present giant nonlinear optical, bistable and asymmetric transmission ...

Bianisotropic Photonic Metamaterials

IEEE Journal of Selected Topics in Quantum Electronics, 2010
In metamaterials, electric (magnetic) dipoles can be excited by the electric (magnetic) component of the incident light field. Moreover, in the description of bianisotropic metamaterials, cross terms occur, i.e., magnetic dipoles can also be excited by the electric-field component of the incident light and vice versa.
