All-photonic integrated circuits are promising platforms for future systems beyond the
limitation of Moore's law. Over the last several decades, one-dimensional (1D) nanowires …

Nanowires supporting propagating surface plasmons can function as nanowaveguides to
realize the light guiding with field confinement beyond the diffraction limit, providing …

Nanoantennas for visible and infrared radiation can strongly enhance the interaction of light
with nanoscale matter by their ability to efficiently link propagating and spatially localized …

Unlike radiowave antennas, so far optical nanoantennas cannot be fed by electrical
generators. Instead, they are driven by light or indirectly via excited discrete states in active …

We push the fabrication limit of gold nanostructures to the exciting sub-nanometer regime, in
which light–matter interactions have been anticipated to be strongly affected by the quantum …

Squeezing light through nanometre-wide gaps in metals can lead to extreme field
enhancements, nonlocal electromagnetic effects and light-induced electron tunnelling. This …

Surface plasmon polaritons are a central concept in nanoplasmonics and have been
exploited to develop ultrasensitive chemical detection platforms, as well as imaging and …

Yagi-Uda antennas are a key technology for efficiently transmitting information from point to
point using radio waves. Since higher frequencies allow higher bandwidths and smaller …

Photonic elements can carry information with a capacity exceeding 1,000 times that of
electronic components, but, due to the optical diffraction limit, these elements are large and …

The conversion of electric power to light is an important scientific and technological
challenge. Advanced experimental methods have provided access to explore the relevant …
