Abstract Shaping and controlling electromagnetic fields at the nanoscale is vital for advancing efficient and compact devices used in optical communications, sensing and metrology, as well as for the exploration of fundamental properties of light-mat

We show how the spin-orbit interaction of light in systems with non-circular symmetry changes optical angular momentum conservation, or even completely breaks it. We demonstrate our claims through phase-resolved near-field measurements and optical fo

Structured illumination microscopy (SIM) improves spatial resolution by folding high-frequency spectral components into the optical system’s passband. While linear SIM is superior in terms of temporal resolution, living-cells imaging compatibility,

In the past decade, the spin-orbit interaction (SOI) of light has been a driving force in the design of metamaterials, metasurfaces, and schemes for light-matter interaction. A hallmark of the spin-orbit interaction of light is the spin-based plasmon

We experimentally demonstrate creation of two-dimentional plasmonic vortex lattices, while controlling the lattice topology. These lattices could drive many nanophotonic applications and bear an uncanny similarity to recently observed magnetic skyrmi

Topological defects play a key role in a variety of physical systems, ranging from high-energy to solid state physics. They yield fascinating emergent phenomena and serve as a bridge between the microspic and macroscopic world. A skyrmion is a unique

We designed and realized a metasurface (manipulating the local geometry) spiral (manipulating the global geometry) plasmonic lens, which fundamentally overcomes the multiple efficiency and functionality challenges of conventional in-plane plasmonic l

High-order optical vortices are inherently unstable, as they tend to split up under perturbation to a series of vortices with unity charge. Control over the perturbation opens up a new degree of freedom to control and tune their location in a 2D-spac
