Coherent perfect absorption mediated anomalous reflection and refraction

Olivier Martin, Shourya Dutta Gupta

We show bending of light on the same side of the normal in a free-standing corrugated metal film under bidirectional illumination. Coherent perfect absorption (CPA) is exploited to suppress the specular zeroth order leading to effective back-bending of lig ...

Molecule-Dependent Plasmonic Enhancement of Fluorescence and Raman Scattering near Realistic Nanostructures

Olivier Martin, Andreas Kern

The enhancement of fluorescence and Raman scattering by plasmonic nanostructures is studied theoretically with special focus on the effects of the observed molecule's properties and the realistic geometry of the plasmonic nanostructure. Numerical experimen ...

Strong enhancement of forbidden atomic transitions using plasmonic nanostructures

Olivier Martin, Andreas Kern

We investigate the mediation of symmetry-forbidden atomic transitions using plasmonic nanostructures. We show that the excitation of the electric dipole-forbidden, quadrupole-allowed 6 2S1/2 − 5 2D5/2 transition in cesium may be enhanced by more than 6 ord ...

Controllable coherent perfect absorption in a composite film

Olivier Martin, Shourya Dutta Gupta

We exploit the versatility provided by metal-dielectric composites to demonstrate controllable coherent perfect absorption (CPA) or anti-lasing in a slab of heterogeneous medium. The slab is illuminated by coherent light from both sides, at the same angle ...

Multipolar effects and strong coupling in hybrid plasmonic metamaterials

Olivier Martin, Arash Farhang

Recently stacked metamaterial structures coupled to a conductive plane have been investigated and have been shown to exhibit the same properties as stacked structures with double the layers, due to dipole mirror coupling. Here we study a system of stacked ...

Fano resonant plasmonic systems: Functioning principles and applications

Olivier Martin, Benjamin Gallinet, Andrea Lovera, Thomas Gerd Siegfried

Using a generalization of Fano formula that includes the intrinsic losses associated with metals, we retrieve the underlying modal structure that produces Fano resonances from the interference between a bright and a dark mode. This knowledge is used to det ...
