We propose a scheme to retrieve the size parameters of a nanoparticle on a glass substrate at a scale much smaller than the wavelength. This is achieved by illuminating the particle using two plane waves to create rich and nontrivial local polarization distributions, and observing the far-field scattering pattern into the substrate. By using this illumination to control the induced complex dipole moment, the exponential decay of power radiated into the supercritical region, as well as…

Near-field spectrum retrieving through non-degenerate coupling emission

Abstract We present a scheme to retrieve the initial spectrum of probe molecules in the near field. This is achieved by replacing conventional glass substrates with a hybrid mode photonics chip to

Momentum-Space Geometric Structure of Helical Evanescent Waves and Its Implications on Near-Field Directionality

In this work, a momentum-space geometrical structure in helical evanescent electromagnetic waves is revealed. It is shown that for every helical evanescent wave on a helicity-dependent half tangent

Polarization-controlled directional scattering for nanoscopic position sensing

TLDR
For controlled excitation of a spherical silicon nanoantenna, this work uses tightly focused radially polarized light to achieve strong lateral directionality and demonstrates in a proof-of-concept experiment that a lateral resolution in the Ångström regime can be achieved.

Quantum state-controlled directional spontaneous emission of photons into a nanophotonic waveguide

TLDR
The directional spontaneous emission of photons by laser-trapped caesium atoms into an optical nanofibre is demonstrated and the spontaneous emission into the counter-propagating guided modes from symmetric to strongly asymmetric, where more than % of the optical power is launched into one or the other direction.

Accurate Feeding of Nanoantenna by Singular Optics for Nanoscale Translational and Rotational Displacement Sensing.

TLDR
It is shown in this Letter that nanoantennas with subwavelength structures can be excited precisely by incident beams with singularity, which can lead to dynamic control of the unidirectional scattering in the far field.

Measuring the transverse spin density of light.

TLDR
The longitudinal electric component of Belinfante's elusive spin momentum density is determined, a solenoidal field quantity often referred to as "virtual" in this work.

Chiral nanophotonic waveguide interface based on spin-orbit interaction of light

TLDR
It is demonstrated that the directional flow of light in a fiber can be controlled by placing a single gold nanoparticle on or near the surface of the fiber by exploiting the chiral properties of light (the spin-orbit interaction) to create a chiral waveguide coupler.

Spin-orbit interactions of light

This Review article provides an overview of the fundamental origins and important applications of the main spin–orbit interaction phenomena in modern optics that play a crucial role at subwavelength

Nanophotonic control of circular dipole emission.

TLDR
The measurements demonstrate the possibility of coupling the spin to photonic pathway and show that, depending on the combination of the local helicity of the mode and the dipole helicity, circular dipoles can couple to left- or rightwards propagating modes with a near-unity directionality.

Polarization tailored light driven directional optical nanobeacon.

TLDR
All-optical control of the emission directivity of a dipole-like nanoparticle with spinning dipole moment sitting on the interface to an optical denser medium is experimentally demonstrated and the polarization dependent coupling to a planar two-dimensional dielectric waveguide is investigated.

Optical diode based on the chirality of guided photons

Photons are nonchiral particles: their handedness can be both left and right. However, when light is transversely confined, it can locally exhibit a transverse spin whose orientation is fixed by the

Spin-orbit coupling in surface plasmon scattering by nanostructures.

TLDR
A reciprocal effect of spin-orbit coupling is demonstrated when the direction of propagation of a surface plasmon wave, which intrinsically has unusual transverse spin, determines a scattering direction ofspin-carrying photons.
