Tunable Quantum Interference in Free Space with a Liquid-Crystal Metagrating
Maria Gorizia Ammendola, Italo Machuca Flores, Sneha Dey +9
Structured optical materials provide a promising platform for photonic quantum information processing in free space. Beam splitters, a fundamental building block of photonic circui…
Skyrmionic polarization textures in structured dielectric planar media
Francesco Di Colandrea, Lorenzo Marrucci, Filippo Cardano
Skyrmionic patterns of optical fields have recently emerged across diverse photonic platforms. Here, we show that such textures also arise in the polarization eigenstates of light…
Large-scale free-space photonic circuits in two dimensions
Maria Gorizia Ammendola, Francesco Di Colandrea, Lorenzo Marrucci +1
Photonic circuits, engineered to couple optical modes according to a specific map, serve as processors for classical and quantum light. The number of components typically scales wi…
Electrically tunable liquid-crystal metasurfaces with patterned birefringence and dichroism
Paola Savarese, Sarvesh Bansal, Maria Gorizia Ammendola +7
Light propagation through artificially patterned anisotropic materials, such as dielectric metasurfaces, enables precise control of the spatio-vectorial properties of optical field…
