Multi-Plane Spatially Resolved Phase Structuring Using Optical Communication Modes
Vinicius S. de Angelis, Maximilian Jeindl, Leonardo A. Ambrosio +3
We present a deterministic framework for three-dimensional beam shaping that enables versatile control of intensity and phase, pixel-by-pixel, across multiple axial planes. Convent…
Silica meta-optics: When high-performance does not need a high-index
Luca Sacchi, Alfonso Palmieri, Vitthal Mishra +3
Metasurfaces -- planar arrays of subwavelength nanostructures -- are typically realized with high-index dielectrics, while low-index platforms are often dismissed for their weaker…
Observation of spatially structured Montgomery effect in free space
Murat Yessenov, Luca Sacchi, Alfonso Palmieri +3
We report the first direct observation of the spatially structured Montgomery effect, a lensless self-imaging phenomenon that generalizes the Talbot effect to aperiodic structures,…
Topology-Optimized Dielectric Cavities for Enhanced Excitonic Light Emission from
Owen Matthiessen, Brandon Triplett, Omer Yesilyurt +14
Photonic inverse design and, especially, topology optimization, enable dielectric cavities with deeply sub-diffraction mode volumes and high quality factors, thus offering a powerf…
Ultrafast space-time optical merons in momentum-energy space
Murat Yessenov, Ahmed H. Dorrah, Cheng Guo +7
Skyrmions, topologically non-trivial localized spin structures, are fertile ground for exploring emergent phenomena in condensed matter physics and next-generation magnetic-memory…
Optimal structured light waves generation in 3D volumes using communication mode optics
Vinicius S. de Angelis, Ahmed H. Dorrah, Leonardo A. Ambrosio +2
Achieving precise control of light intensity in 3D volumes is highly in demand in many applications in optics. Various wavefront shaping techniques have been utilized to reconstruc…
