Abstract While optical tweezers (OT) are mostly used for confining smaller size particles, the counter-propagating (CP) dual-beam traps have been a versatile method for confining both small and larger size particles including biological specimen. How

We theoretically study spherical cavities composed of hyperbolic metamaterials with indefinite permittivity tensors. Such cavities are capable of electrodynamically confining fields with deep subwavelength cavity sizes. The supported resonant modes a

The well-known counter-propagating optical traps require the beams to be symmetrical for 3D trapping, resulting in a highly-sensitive system. Here, we study an easy-to-align counter-propagating trap with a broken symmetry, demonstrating stable trappi

We present a numerical study of the linear and nonlinear diffraction and focusing properties of dielectric metasurfaces consisting of silicon microcylinder arrays resting on a silicon substrate. Upon diffraction, such structures lead to the formation

We present the theory of parametrically resonant surface plasmon polaritons. We show that a temporal modulation of the dielectric properties of the medium adjacent to a metallic surface can lead to efficient energy injection into the surface plasmon

We discuss a new class of nonlinear absorbers termed Plasmonic Parametric Absorbers (PPA) relying on the recently introduced concept of Plasmonic Parametric Resonance (PPR). In contrast with conventional localized plasmonic resonances, whereby modes
