TL;DR: In principle, electrically gated phase and amplitude control allows for electrical addressability of individual metasurface elements and opens the path to applications in ultrathin optical components for imaging and sensing technologies, such as reconfigurable beam steering devices, dynamic holograms, tunable ultrathins, nanoprojectors, and nanoscale spatial light modulators.

TL;DR: An ultracompact PlasMOStor, a plasmon slot waveguide field-effect modulator based on a transparent conducting oxide active region, is experimentally demonstrated, demonstrating field- effect dynamics giving rise to modulation with high dynamic range, low waveguide loss and large modulation strength.

TL;DR: It is shown that adding chirality to the cladding surrounding the core may provide another route to manipulating the transmission of light, and an effect that appears in continuously twisted photonic crystal fiber is reported.

TL;DR: In this article, the authors present experimental results on coupling to surface plasmon modes on gold nanowires selectively introduced into polarization-maintaining photonic crystal fibers, which can be potentially used as in-fiber wavelength-dependent filters and polarizers and as near-field tips for sub-wavelength-scale imaging.

TL;DR: A novel splicing-based pressure-assisted melt-filling technique for creating metallic nanowires in hollow channels in microstructured silica fibers that suggest applications in fields such as nonlinear plasmonics, near-field scanning optical microscope tips, cylindrical polarizers, optical sensing and telecommunications.
