Proceedings ArticleDOI
High-Q resonance train in a plasmonic metasurface
Saad-Bin-Alam,Orad Reshef,Mikko J. Huttunen,Graham Carlow,Brian T. Sullivan,Jean-Michel Ménard,Ksenia Dolgaleva,Robert W. Boyd +7 more
TL;DR: A plasmonic surface that supports a series of high-quality factor (Q ≈ 100) surface lattice resonances was demonstrated in this article. But the performance of this surface was limited by tuning the thickness of the top-cladding layer to confine higher order diffraction orders.
Journal ArticleDOI
Dark and bright modes, and their coherent control in dipolar metasurface bilayers
TL;DR: In this paper , a semianalytical model describing the reflection and absorption spectra of dipolar bilayer metasurfaces was derived, showing how radiative coupling between the layers can result in the formation of nonradiative dark modes which can contribute significantly to the optical response of the system.
Proceedings Article
Backward air lasing with femtosecond pumping
TL;DR: In this paper, the authors used a two-step excitation scheme involving dissociation of molecular oxygen or nitrogen and subsequent two-photon pumping of the resulting oxygen and nitrogen atoms by laser radiation at specific deep-UV wavelengths.
Proceedings ArticleDOI
Plasmonic Metasurfaces for the Generation of Optical Orbital Angular Momentum
Sebastian A. Schulz,Ebrahim Karimi,Israel De Leon,Frédéric Bouchard,Hammam Qassim,Jeremy Upham,Robert W. Boyd +6 more
TL;DR: In this article, the authors demonstrate the generation of optical orbital angular momentum at visible wavelengths through spin-to-orbit coupling in an ultrathin plasmonic metasurface.
Proceedings ArticleDOI
Demonstration of a slow-light laser radar (SLIDAR)
TL;DR: In this article, a multi-aperture slow-light laser radar (SLIDAR) system is proposed to control the relative group delay among various apertures while the relative phases among aperture remain locked.
