Nature Photonics spoke to Pierre Berini — pioneer of plasmon waveguides — to get some perspective on how nanophotonics has evolved over the past decade and where it is heading.
'Nanophotonics' is no longer just the realm of plasmonics researchers. Fields like metamaterials and 'flat' two-dimensional systems based on atomically thin materials are expanding the boundaries of nanophotonics.
A network of optical parametric oscillators has been harnessed to find solutions to a complex problem in statistical physics that is difficult to solve using numerical computing algorithms.
The optical properties of graphene and emerging two-dimensional materials including transition metal dichalcogenides are reviewed with an emphasis on nanophotonic applications.
Recent developments in probe-based near-field microscopy are reviewed, including techniques for determining the phase, amplitude and separate components of the electric and magnetic field.
Metamaterials enable the tailoring of properties like dielectric permittivity and magnetic permeability. Electromagnetic excitations of metamaterial constituents and their interactions are reviewed, as well as promising future directions.
Solution-processed small-molecule solar cells with almost 100% internal quantum efficiency and a power conversion efficiency of 9% are reported. The cells make use of a donor molecule called DRCN7T and use PC71BM as an acceptor.
The authors report a semiconductor injection laser with a continuous wave emission spanning more than one octave, from 1.64 THz to 3.35 THz, with optical powers in the milliwatt range and more than 80 modes above threshold.
