On-Chip Integrated, Silicon–Graphene Plasmonic Schottky Photodetector with High Responsivity and Avalanche Photogain
TLDR
An on-chip integrated metal graphene–silicon plasmonic Schottky photodetector with 85 mA/W responsivity at 1.55 μm and 7% internal quantum efficiency is reported, paving the way to graphene integrated silicon photonics.
Nanoscale plasmonic memristor with optical readout functionality.
TLDR
A nanoscale resistive random access memory (RRAM) electronic device integrated with a plasmonic waveguide providing the functionality of optical readout and the experimental characterization shows optical bistable behavior between these levels of transmission in addition to well-defined hysteresis.
Locally oxidized silicon surface-plasmon Schottky detector for telecom regime.
TLDR
An on-chip nanoscale silicon surface-plasmon Schottky photodetector based on internal photoemission process and operating at telecom wavelengths and can be integrated with other nanophotonic and nanoplasmonic structures for the realization of monolithic opto-electronic circuitry on- chip.
Plasmonic metasurfaces for coloration of plastic consumer products.
TLDR
This work utilizes the hybridization between LSPR modes in aluminum nanodisks and nanoholes to design and fabricate bright angle-insensitive colors that may be tuned across the entire visible spectrum.
Resonant laser printing of structural colors on high-index dielectric metasurfaces
TLDR
Laser-printable high-index dielectric color metasurfaces are scalable to a large area and open a new paradigm for printing and decoration with nonfading and vibrant colors.
Nanoscale light–matter interactions in atomic cladding waveguides
TLDR
This work constructs an efficient and flexible platform for tailored light–vapour interactions on a chip and demonstrates light–matter interactions in an atomic cladding waveguide, consisting of a silicon nitride nano-waveguide core with a rubidium vapour cladding.
Generation and tight focusing of hybridly polarized vector beams
TLDR
Tight focusing analysis show polarization distribution with 3D orientation and space variant ellipticity, which may be useful for particle orientation analysis, microscopy and atomic systems.
Demonstration of nanofocusing by the use of plasmonic lens illuminated with radially polarized light.
TLDR
The results demonstrate the advantage of using radially polarized light for nanofocusing applications involving surface plasmon polaritons, and verify that the focal spot maintains its width along the optical axis of the plAsmonic lens.
Fano resonances and all-optical switching in a resonantly coupled plasmonic-atomic system.
TLDR
By exploiting the plasmonic enhancement of light-matter interactions, this work demonstrates all-optical control of the Fano resonance by introducing an additional pump beam to control the lineshape and the dispersion of this hybrid system.
Effect of radial polarization and apodization on spot size under tight focusing conditions.
TLDR
It is shown that for a clear aperture geometry, illuminating the lens by linear or circular polarization is preferable over radial polarization for spot size reduction applications, and the longitudinal component generated by radially polarized illumination produces the narrowest spot size for wide range of geometries.
