Highly sensitive beam steering with plasmonic antenna
Guanghao Rui,Qiwen Zhan +1 more
TL;DR: The short effective wavelength of the surface plasmon polaritons (SPPs) mode supported by the metallic waveguide is exploited to dramatically miniaturize the device and improve the sensitivity of the beam steering.
Journal ArticleDOI
Symmetric Meta‐Absorber‐Induced Superchirality
Guanghao Rui,Guanghao Rui,Haifeng Hu,Matthew Singer,Yi‐Jun Jen,Qiwen Zhan,Qiwen Zhan,Qiaoqiang Gan,Qiaoqiang Gan +8 more
Journal ArticleDOI
High efficiency plasmonic probe design for parallel near-field optics applications
TL;DR: A high efficiency plasmonic near-field probe that integrates a spiral plAsmonic lens and a sharp conical tip under circular polarized illumination and can be made in an array format that is suitable for large area parallel near- field optics applications such as lithography and microscopy is studied.
Journal ArticleDOI
Manipulation of dielectric Rayleigh particles using highly focused elliptically polarized vector fields.
TL;DR: It is shown that the additional degree of freedom provided by the elliptically polarized vector field allows one to control the spatial structure of polarization, to engineer the focusing field, and to tailor the optical force and torque on a dielectric Rayleigh particle.
Journal ArticleDOI
Enhanced sensitivity of the Z-scan technique on saturable absorbers using radially polarized beams
TL;DR: In this paper, the authors investigated the saturable absorption properties of layered WS2 nanosheets in aqueous suspension by performing the radially polarized-beam Z-scan measurements with femtosecond laser pulses in the near infrared region.
