Plasmonic Purcell factor and coupling efficiency to surface plasmons. Implications for addressing and controlling optical nanosources
G. Colas des Francs, J. Barthes, A. Bouhelier +2
The Purcell factor is a key quantity in cavity quantum electrodynamics (cQED) that quantifies the coupling rate between a dipolar emitter and a cavity mode. Its simple form $…
Momentum-space spectroscopy for advanced analysis of dielectric-loaded surface plasmon polariton coupled and bent waveguides
K. Hassan, A. Bouhelier, T. Bernardin +4
We perform advanced radiation leakage microscopy of routing dielectric-loaded plasmonic waveguiding structures. By direct plane imaging and momentum-space spectroscopy, we analyze…
Mie plasmons: modes volumes, quality factors and coupling strengths (Purcell factor) to a dipolar emitter
G. Colas des Francs, S. Derom, R. Vincent +2
Using either quasi-static approximation or exact Mie expansion, we characterize the localized surface plasmons supported by a metallic spherical nanoparticle. We estimate the quali…
Purcell factor for point-like dipolar emitter coupling to 2D-plasmonic waveguides
J. Barthes, G. Colas des Francs, A. Bouhelier +2
We theoretically investigate the spontaneous emission of a point--like dipolar emitter located near a two--dimensional (2D) plasmonic waveguide of arbitrary form. We invoke an expl…
Modulation of surface plasmon coupling-in by one-dimensional surface corrugation
F. Lopez-Tejeira, Sergio G. Rodrigo, L. Martin-Moreno +10
Surface plasmon-polaritons have recently attracted renewed interest in the scientific community for their potential in sub-wavelength optics, light generation and non-destructive s…
Efficient unidirectional nanoslit couplers for surface plasmons
F. Lopez-Tejeira, Sergio G. Rodrigo, L. Martin-Moreno +9
Plasmonics is based on surface plasmon polariton (SPP) modes which can be laterally confined below the diffraction limit, thereby enabling ultracompact optical components. In order…
