Spontaneous Raman Scattering under Vibrational Strong Coupling: The Critical Role of Polariton Spatial Mode Coherence
Maxime Dherbécourt, Joël Bellessa, Clémentine Symonds +2
Resonant coupling of a vibration to a cavity mode has been reported to dramatically modify spontaneous Raman scattering, but subsequent studies have produced conflicting results. I…
Taming Friedrich-Wintgen interference in resonant metasurface: vortex laser emitting at on-demand tilted-angle
Raphael Mermet-Lyaudoz, Clémentine Symond, Florian Berry +7
Friedrich-Wintgen (FW) interference is an atypical coupling mechanism that grants loss exchange between leaky resonances in non-Hermitian classical and quantum systems. Intriguingl…
Tamm Cavity in the Terahertz Spectral Range
Simon Messelot, Clémentine Symonds, Joël Bellessa +5
Electromagnetic resonators, which are based on optical cavities or electronic circuits, are key elements to enhance and control light-matter interaction. In the THz range, current…
Tamm plasmons in metal/nanoporous GaN distributed Bragg reflector cavities for active and passive optoelectronics
Guillaume Lheureux, Morteza Monavarian, Ryan Anderson +7
We investigate Tamm plasmon (TP) modes in a metal/semiconductor distributed Bragg reflector (DBR) interface. A thin Ag (silver) layer with an optimized thickness (~ 55 nm from simu…
Anisotropy and controllable band structure in supra-wavelength polaritonic metasurfaces
K. Chevrier, J. M. Benoit, C. Symonds +3
In this letter we exploit the extended coherence length of mixed plasmon/exciton states to generate active metasurfaces. For this purpose, periodic stripes of organic dye are depos…
Tamm plasmon Photonic Crystals : from Bandgap Engineering to Defect Cavity
Lydie Ferrier, Hai Son Nguyen, Cécile Jamois +4
We report for the first time the bandgap engineering of Tamm plasmon photonic crystals - Tamm plasmon structures of which the metalic layer is periodically patterned into lattice o…
Chiral optical Local Density of States in spiral plasmonic cavity
Aline Pham, Martin Berthel, Quanbo Jiang Joel Bellessa +3
We introduce a new paradigm: the chiral electromagnetic local density of states (LDOS) in a spiral plasmonic nanostructure. In both classical and quantum regimes, we reveal using s…
Highly efficient singular surface plasmon generation by achiral apertures
Quanbo Jiang, Aline Pham, Joel Bellessa +3
We report a highly efficient generation of singular surface plasmon (SP) field by an achiral plasmonic structure consisting of -shaped apertures. Our quantitative analysis based…
Directional and singular surface plasmon generation in chiral and achiral nanostructures demonstrated by Leakage Radiation Microscopy
Quanbo Jiang, Aline Pham, Martin Berthel +4
In this paper, we describe the implementation of leakage radiation microscopy (LRM) to probe the chirality of plasmonic nanostructures. We demonstrate experimentally spin-driven di…
Coherence and aberration effects in surface plasmon polariton imaging
Martin Berthel, Quanbo Jiang, Camille Chartrand +4
We study theoretically and experimentally coherent imaging of surface plasmon polaritons using either leakage radiation microscopy through a thin metal film or interference microsc…
Coherent emission from a disordered organic semiconductor induced by strong coupling with surface plasmons
S. Aberra Guebrou, C. Symonds, E. Homeyer +4
In this Letter we show that the strong coupling between a disordered set of molecular emitters and surface plasmons leads to the formation of spatially coherent hybrid states exten…
Full control of spontaneous emission in confined Tamm plasmon structures
O. Gazzano, S. Michaelis de Vasconcellos, K. Gauthron +6
We demonstrate strong confinement of the optical field by depositing a micron sized metallic disk on a planar interferential mirror. Zero dimensional Tamm plasmon modes are evidenc…
Exciton/plasmon polaritons in GaAs/GaAlAs heterostructures near a metallic layer
J. Bellessa, C. Symonds, C. Meynaud +5
We report on the strong coupling between inorganic quantum well excitons and surface plasmons. For that purpose a corrugated silver film was deposited on the top of a heterostructu…
Peak-effect and surface crystal-glass transition for surface-pinned vortex array
Bernard Placais, Norbert Lutke-Entrup, Joel Bellessa +3
We present a theoretical and experimental study of the peak effect in the surface pinning of vortices. It is associated with a sharp transition in the vortex slippage length which…
Peak-effect and surface crystal-glass transition for surface-pinned vortex array
B. Placais, N. Lutke-Entrup, J. Bellessa +3
The peak effect has been investigated in clean Nb crystals with artificially corrugated surfaces by measuring the linear surface impedance in the 1kHz-1MHz frequency range. From a…
