Journal ArticleDOI
The Fano resonance in plasmonic nanostructures and metamaterials
Boris Luk'yanchuk,Nikolay I. Zheludev,Stefan A. Maier,Naomi J. Halas,Peter Nordlander,Harald Giessen,Chong Tow Chong,Chong Tow Chong +7 more
TL;DR: The steep dispersion of the Fano resonance profile promises applications in sensors, lasing, switching, and nonlinear and slow-light devices.
Journal ArticleDOI
Infrared Perfect Absorber and Its Application As Plasmonic Sensor
TL;DR: A perfect plasmonic absorber is experimentally demonstrated at lambda = 1.6 microm, its polarization-independent absorbance is 99% at normal incidence and remains very high over a wide angular range of incidence around +/-80 degrees.
Journal ArticleDOI
Plasmonic analogue of electromagnetically induced transparency at the Drude damping limit.
Na Liu,Lutz Langguth,Thomas Weiss,Jürgen Kästel,Michael Fleischhauer,Tilman Pfau,Harald Giessen +6 more
TL;DR: A nanoplasmonic analogue of EIT is experimentally demonstrated using a stacked optical metamaterial to achieve a very narrow transparency window with high modulation depth owing to nearly complete suppression of radiative losses.
Journal ArticleDOI
Planar metamaterial analogue of electromagnetically induced transparency for plasmonic sensing.
Na Liu,Thomas Weiss,Martin Mesch,Lutz Langguth,Ulrike Eigenthaler,Michael Hirscher,Carsten Sönnichsen,Harald Giessen +7 more
TL;DR: A planar metamaterial analogue of electromagnetically induced transparency at optical frequencies is experimentally demonstrated and yields a sensitivity of 588 nm/RIU and a figure of merit of 3.8.
Journal ArticleDOI
Nanoantenna-enhanced gas sensing in a single tailored nanofocus
TL;DR: This work places a single palladium nanoparticle near the tip region of a gold nanoantenna and detects the changing optical properties of the system upon hydrogen exposure, demonstrating antenna-enhanced hydrogen sensing at the single-particle level.
