Plasmonic photo-current in freestanding monolayered gold nanoparticle membranes

Jürgen Brugger

We report on photo-current generation in freestanding monolayered gold nanoparticle membranes excited by using a focused laser beam. The absence of a substrate leads to a 50% increase of the photo-current at the surface plasmon resonance. This current is a ...

Ultrafast imaging of plasmons in a transmission electron microscope

Fabrizio Carbone, Gabriele Berruto, Tom Theodorus Antonius Lummen

Miniaturized plasmonic and photonic integrated circuits are generally considered as the core of future generations of optoelectronic devices, due to their potential to bridge the size-compatibility gap between photonics and electronics. However, as the nan ...

SPR Sensor with Ultranarrow Magnetoplasmonic Resonance

Pavel Kapralov

We present the results of experimental investigations of the ultralong-range propagating magnetoplasmons in the specially designed heterostructure. The propagation distance of the surface plasmon increases up to 35 pm due to the inclusion of the photonic c ...

Magneto-optical plasmonic heterostructure with ultranarrow resonance for sensing applications

Giovanni Dietler, Pavel Kapralov

Currently, sensors invade into our everyday life to bring higher life standards, excellent medical diagnostic and efficient security. Plasmonic biosensors demonstrate an outstanding performance ranking themselves among best candidates for different applica ...

Plasmon coupling in extended structures: Graphene superlattice nanoribbon arrays

Hatice Altug, Daniel Rodrigo Lopez

Interaction between localized plasmons in isolated proximal nanostructures is a well-studied phenomenon. Here we explore plasmon-plasmon interactions in connected extended systems. Such systems can now be easily produced experimentally using graphene. Howe ...

Imaging and controlling plasmonic interference fields at buried interfaces

Fabrizio Carbone, Gabriele Berruto, Brett Eugene Barwick, Tom Theodorus Antonius Lummen

Capturing and controlling plasmons at buried interfaces with nanometre and femtosecond resolution has yet to be achieved and is critical for next generation plasmonic devices. Here we use light to excite plasmonic interference patterns at a buried metal-di ...

We numerically investigate the second harmonic generation from different plasmonic systems and evidence the key role played in their nonlinear response by the phase at the fundamental wavelength. In the case of a single plasmonic nanorod, the interference ...

Revisiting Newton’s rings with a plasmonic optical flat for high-accuracy surface inspection

Olivier Martin, Xiaolong Wang, Jie Bian

Two parallel optical surfaces often exhibit colorful fringes along the lines of equal thickness because of the interference of light. This simple phenomenon allows one to observe subwavelength corrugations on a reflective surface by simply placing on it a ...

Springer2016

Biosensors based on the localized surface plasmon resonance (LSPR) of individual metallic nanoparticles promise to deliver modular, low-cost sensing with high-detection thresholds. However, they continue to suffer from relatively low sensitivity and figure ...

We image the dispersion of surface plasmon polaritons in gold and silver thin films of 30 and 50 nm thickness, using angle-resolved white light spectroscopy in the Kretschmann geometry. Calibrated dispersion curves are obtained over a wavelength range span ...
