Entangled photon states are a fundamental resource for optical quantum technologies and investigating the predictions of mechanics. Up to now such mainly generated in macroscopic nonlinear systems with elaborately tailored properties. In this theoretical work, we extend understanding on generation entangled photonic toward nanoscale regime by properties photon-pair sub-wavelength nanoresonators. Taking materials Zinc-Blende structure as an example, reveal that can naturally generate various...
Huygens sources are elements that scatter light in the forward direction as used Huygens-Fresnel principle. They have remained fictitious until recently where experimental systems been fabricated. In this letter, we propose isotropic meta-atoms act sources. Using clusters of plasmonic or dielectric colloidal particles, dipoles resonate at visible frequencies can be achieved with scattering cross-sections high 5 times geometric cross-section particle surpassing anything achievable a...
Abstract The generation in artificial composites of a magnetic response to light, comparable magnitude with the natural electric response, may offer an invaluable control parameter for fine steering light at nanoscale. In many experimental realizations, however, meta-atoms is too weak so that there need new designs increased polarizability. Numerical simulations show geometrical plasmonic nanostructures based on Platonic solids are excellent candidates production strong optical magnetism...
Relating the electromagnetic scattering and absorption properties of an individual particle to reflection transmission coefficients a two-dimensional material composed these particles is crucial concept that has driven both fundamental applied physics. It at heart characterization as well phase amplitude engineering wave. Here we propose multipolar description across monolayer using vector spherical harmonic decomposition. This enables us provide generalized condition for perfect which...
Abstract Periodic arrays of anisotropic silver nanoparticles having peculiar optical properties are fabricated at a macroscopic scale. The proposed scalable method is based on temperature‐assisted solid‐state dewetting continuous thin layer deposited silica substrate patterned by the nanoimprint technique. resulting shaped like diamonds and half‐embedded into silica. A period‐dependent optimum in film thickness for quality spatial organization found discussed terms thermodynamics and, first...
An emulsion formulation process, allowing for large scale production, yields tailored colloidal nanoresonators with electric and magnetic resonances engineered so that the resonators act as strong isotropic Huygens scatterers.
We present spherical clusters, composed by dielectric or metallic inclusions, as a new kind of efficient and isotropic Huygens sources. demonstrate that this design can allow large multimode overlapping the electric magnetic resonances excited at visible frequencies. They may also serve building blocks for metasurface applications. investigate their possible uses in high transmittance devices requiring local phase control, thin absorber metalattices. are particularly suited to bottom-up...
