Subwavelength Energy Transport Along a Dielectric Nanoparticle Chain in a Metal Slot
IEEE Photonics Journal, 2013 Subwavelength energy transportation along a dielectric nanoparticle chain in a metal slot is investigated. It is demonstrated that subwavelength resonance modes with nanoscale confinement could be well achieved in the proposed waveguide, free from the ...

Single-Cycle Gap Soliton in a Subwavelength Structure [PDF]
Physical Review Letters, 2010 We demonstrate that a single sub-cycle optical pulse can be generated when a pulse with a few optical cycles penetrates through resonant two-level dense media with a subwavelength structure. The single-cycle gap soliton phenomenon in the full Maxwell-Bloch equations without the frame of slowly varying envelope and rotating wave approximations is ...

Antireflective Multilayer Surface with Self-Cleaning Subwavelength Structures [PDF]
ACS Photonics, 2021 The suppression of optical reflection from a surface is essential in many applications, ranging from displays with reduced disturbance from ambient light to high-efficiency photovoltaic cells and stable light detection and ranging (LIDAR) systems. Traditionally, antireflection (AR) surfaces are made of multilayer (ML) coatings that produce destructive ...

Multi-wavelength focusing based on nanoholes
New Journal of Physics, 2020 A kind of controllable multi-wavelength focusing metalenses is proposed. The proposed metalenses consist of identical nanometer holes etched in silver film and the beam focusing at three primary wavelengths is controlled without additional phase ...

Keeping Good Sensing Performance of Metal–Dielectric–Metal Waveguides After Coating Treatment
IEEE Photonics Journal, 2017 Good sensing performance is observed in metal–dielectric–metal (MDM) waveguides in recent research. However, Ag will be oxidized in air. The oxidization layer makes the sensing performance not as high as before.

Compressive imaging of subwavelength structures: periodic rough surfaces [PDF]
Journal of the Optical Society of America A, 2012 A compressed sensing scheme for near-field imaging of corrugations of relative sparse Fourier components is proposed. The scheme employs random sparse measurement of near field to recover the angular spectrum of the scattered field. It is shown heuristically and numerically that under the Rayleigh hypothesis the angular spectrum is compressible and ...
