Polarisation Singularities of Gravitational Waves
Claire Rigouzzo, Sebastian Golat, Alex J. Vernon +3
Departure from idealised plane waves gives rise to intricate geometric structures in wave fields. One such structure is the polarisation singularity, which emerges when multiple mo…
Optical multipolar torque in structured electromagnetic fields: on `helicity gradient' torque, quadrupolar torque and the spin of field gradient
Lei Wei, Francisco J. Rodríguez Fortuño
Structured light mechanically interacts with matter via optical forces and torques. The optical torque is traditionally calculated via the flux of total angular momentum (AM) into…
Transverse spinning of unpolarized light
J. S. Eismann, L. H. Nicholls, D. J. Roth +6
It is well known that spin angular momentum of light, and therefore that of photons, is directly related to their circular polarization. Naturally, for totally unpolarized light, p…
Exploiting metamaterials, plasmonics and nanoantennas concepts in silicon photonics
Francisco J. Rodríguez-Fortuño, Alba Espinosa-Soria, Alejandro Martínez
The interaction of light with subwavelength metallic nano-structures is at the heart of different current scientific hot topics, namely plasmonics, metamaterials and nanoantennas.…
Near-Field Directionality Beyond the Dipole Approximation: Electric Quadrupole and Higher-Order Multipole Angular Spectra
J. Enrique Vázquez-Lozano, Alejandro Martínez, Francisco J. Rodríguez-Fortuño
Within the context of spin-related optical phenomena, the near-field directionality is generally understood from the quantum spin Hall effect of light, according to which the trans…
Experimental demonstration of linear and spinning Janus dipoles for polarisation and wavelength selective near-field coupling
Michela F. Picardi, Martin Neugebauer, Joerg S. Eismann +4
The electromagnetic field scattered by nano-objects contains a broad range of wave vectors and can be efficiently coupled to waveguided modes. The dominant contribution to scatteri…
Interferometric evanescent wave excitation of nano-antenna for ultra-sensitive displacement and phase metrology
Lei Wei, Anatoly V. Zayats, Francisco J. Rodríguez-Fortuño
We propose a method for ultra-sensitive displacement and phase metrology based on the interferometric evanescent wave excitation of nano-antennas. We show that with a proper choice…
Angular momenta, helicity, and other properties of dielectric-fiber and metallic-wire modes
M. F. Picardi, K. Y. Bliokh, F. J. Rodríguez-Fortuño +2
Spin and orbital angular momenta (AM) of light are well studied for free-space electromagnetic fields, even nonparaxial. One of the important applications of these concepts is the…
Directional scattering from particles under evanescent wave illumination: the role of reactive power
Lei Wei, Michela F. Picardi, Jack J. Kingsley-Smith +2
Study of photonic spin-orbital interactions, which involves control of the propagation and spatial distributions of light with the polarization of electromagnetic fields, is not on…
Electric current induced unidirectional propagation of surface plasmon-polaritons
K. Y. Bliokh, F. J. Rodríguez-Fortuño, A. Y. Bekshaev +2
Nonreciprocity and one-way propagation of optical signals is crucial for modern nanophotonic technology, and is typically achieved using magneto-optical effects requiring large mag…
Janus and Huygens' dipolar sources for near-field directionality
Michela F. Picardi, Anatoly V. Zayats, Francisco J. Rodríguez-Fortuño
Controlling directionality of emission, scattering and waveguiding is an important requirement in quantum optical technology, integrated photonics and new metasurface designs, as w…
Two-dimensional wave propagation without anomalous dispersion
Carl M. Bender, Francisco J. Rodriguez, Sarben Sarkar +1
In two space dimensions and one time dimension a wave changes its shape even in the absence of a dispersive medium. However, this anomalous dispersive behavior in empty two-dimensi…
Spin-orbit interactions of light
K. Y. Bliokh, F. J. Rodriguez-Fortuno, F. Nori +1
Light carries spin and orbital angular momentum. These dynamical properties are determined by the polarization and spatial degrees of freedom of light. Modern nano-optics, photonic…
Sorting polarized photons with a single scatterer
Francisco J. Rodríguez-Fortuño, Daniel Puerto, Amadeu Griol +3
Intuitively, light impinging on a spatially symmetric object will be scattered symmetrically. This intuition can fail at the nanoscale if the polarization of the incoming light is…
Electric Levitation Using Epsilon-Near-Zero Metamaterials
Francisco J. Rodríguez-Fortuño, Ashkan Vakil, Nader Engheta
Levitation of objects with action at a distance has always been intriguing to humans. Several ways to achieve this, such as aerodynamic, acoustic, or electromagnetic methods, inclu…
