Antireflection by design in bilayer metasurfaces
Jaewon Oh, Davide Cassara, Alfonso Palmieri +5
Antireflection coatings are ubiquitous in optical systems, where they maximize transmission and suppress undesirable reflections by impedance-matching uniform interfaces. Extending…
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…
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…
Free-standing bilayer metasurfaces in the visible
Ahmed H. Dorrah, Joon-Suh Park, Alfonso Palmieri +1
Mult-layered meta-optics have enabled complex wavefront shaping beyond their single layer counterpart owing to the additional design variables afforded by each plane. For instance,…
Shape optimization for high efficiency metasurfaces: theory and implementation
P. Dainese, L. Marra, D. Cassara +7
Complex non-local behavior makes designing high efficiency and multifunctional metasurfaces a significant challenge. While using libraries of meta-atoms provide a simple and fast i…
Rotatum of Light
Ahmed H. Dorrah, Alfonso Palmieri, Lisa Li +1
Vortices are ubiquitous in nature and can be observed in fluids, condensed matter, and even in the formation of galaxies. Light, too, can evolve like a vortex. Optical vortices are…
Do bilayer metasurfaces behave as a stack of decoupled single-layer metasurfaces?
Alfonso Palmieri, Ahmed H. Dorrah, Jun Yang +3
Flat optics or metasurfaces have opened new frontiers in wavefront shaping and its applications. Polarization optics is one prominent area which has greatly benefited from the shap…
Metasurfaces for free-space coupling to multicore fibers
Jaewon Oh, Jun Yang, Louis Marra +4
Space-division multiplexing (SDM) with multicore fibers (MCFs) is envisioned to overcome the capacity crunch in optical fiber communications. Within these systems, the coupling opt…
Metasurface-enabled compact, single-shot and complete Mueller matrix imaging
Aun Zaidi, Noah A. Rubin, Maryna L. Meretska +4
When light scatters off an object its polarization, in general, changes - a transformation described by the object's Mueller matrix. Mueller matrix imaging polarimetry is an import…
Point singularity array with metasurfaces
Soon Wei Daniel Lim, Joon-Suh Park, Dmitry Kazakov +4
Phase singularities are loci of darkness surrounded by monochromatic light in a scalar field, with applications in optical trapping, super-resolution imaging, and structured light-…
Roadmap on spatiotemporal light fields
Yijie Shen, Qiwen Zhan, Logan G. Wright +42
Spatiotemporal sculpturing of light pulse with ultimately sophisticated structures represents the holy grail of the human everlasting pursue of ultrafast information transmission a…
Roadmap on multimode light shaping
Marco Piccardo, Vincent Ginis, Andrew Forbes +35
Our ability to generate new distributions of light has been remarkably enhanced in recent years. At the most fundamental level, these light patterns are obtained by ingeniously com…
Jones matrix holography with metasurfaces
Noah A. Rubin, Aun Zaidi, Ahmed Dorrah +2
We propose a new class of computer generated holograms whose far fields possess designer-specified polarization response. We dub these Jones matrix holograms. We provide a simple p…
Evolution of orbital angular momentum in three-dimensional structured light
Ahmed H. Dorrah, Carmelo Rosales-Guzmán, Andrew Forbes +1
Light beams with an azimuthal phase dependency of have helical phase fronts and thus carry orbital angular momentum (OAM), a strictly conserved quantity with propagati…
