Photonics of time modulated media<\/h3>\n\n\n\n
\"\"<\/td>\nVariations in material properties in space as well as time offer new design possibilities and physical effects. For instance, we have shown that modulated metamaterials exhibit the Fresnel drag effect of light, dictated by special relativity and characteristic of moving media. On the other hand, luminal space-time modulations yield a generalization of the parametric amplifier, enabling broadband and non-reciprocal amplification.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Topological photonics<\/strong><\/p>\n

Photonics gives plenty of degrees of freedom to explore topological physics. For instance, it gives access to experimentally realizable topological “particles” which host quantized topological edge modes.

Transformation Optics<\/h3>\n

Transformation Optics is a theoretical tool that yields the required electromagnetic parameters that a metamaterial should have given a desired functionality, or, alternatively, allows for the analytical study of plasmonic nanostructures and metasurfaces.<\/p>\n\n\n\n
\"\"<\/td>\nGraphene Plasmonic Metasurfaces
\n<\/strong>Periodically doped graphene can host surface plasmon excitations which enable very large absorption cross sections even for this atomically-thin materal. The optical response of these metasurfaces can be analytically modelled with Transformation Optics:

\n<\/strong>Plasmonic surfaces with periodic singularities in the form of sharp edges, touching points or suppressed conductivity possess broadband optical spectra as opposed to conventional metasurfaces which are narrowband. Transformation Optics gives an understanding of these effects in terms of a hidden dimension, see:

Plasmonics<\/h3>\n\n\n\n
\"\"<\/td>\nLight interacting with metal nanostructures can drive the conduction electrons to oscillate forming a surface plasmon polariton which propagates along metal surfaces or is localized on a nanoparticle. This enables the confinement of light at subwavelength volumes, beyond the diffraction limit, where it can be manipulated or interact with emitters such as molecules or quantum dots.

Plasmonic metamaterials<\/h3>\n

Metamaterials are composite materials whose electromagnetic properties are determined by their artificial structuring rather than by their chemical composition. As such, they enable optical properties that cannot be found in naturally occurring materials, such as negative refraction or perfect lensing. Some of my interests and research highlights in this area include spoof plasmons. Spoof plasmons mimick the optical properties of surface plasmons but at lower frequencies. They enable for instance surface plasmons with magnetic properties. See e.g.,<\/p>\n
