Vector beams, and in particular vector vortex beams, have found many applications in recent
times, both as classical fields and as quantum states. While much attention has focused on …

Super-resolution optical microscopy, which gives access to finer details of objects, is highly
desired for fields of nanomaterial, nanobiology, nanophotonics, etc. Many efforts, including …

Microscopic techniques based on nonlinear optical processes provide alternative ways to
visualize natural and artificial nanoscopic systems with minimum disturbance. In such …

Nonlinear metasurfaces with high conversion efficiencies have been vastly investigated.
However, strong dynamic tunability of such devices is limited in conventional passive …

We use second-harmonic generation (SHG) with focused vector beams to investigate
individual vertically aligned GaAs nanowires. Our results provide direct evidence that SHG …

We generate a new kind of azimuthal-variant vector field with a distribution of states of
polarization (SoPs) described by the square of the azimuthal angle. Owing to asymmetrical …

We present a method of shaping three-dimensional (3D) vector beams with prescribed
intensity distribution and controllable polarization state variation along arbitrary curves in …

Plasmonics is the study of the collective oscillations of free electrons in metals that can be
resonantly excited at optical frequencies. These oscillations exhibit unique optical properties …

Describing a class of beams with space-variant polarization, vector beams find many
applications in both classical and quantum optics. However, simultaneous manipulation of …

We present an arbitrary vector field with hybrid polarization based on the combination of a
pair of orthogonal elliptically polarized base vectors on the Poincaré sphere. It is shown that …
