Bandwidth bounds for wide-field-of-view dispersion-engineered achromatic metalenses
Kunal Shastri, Francesco Monticone
Optical systems with wide field-of-views (FOV) are crucial for many applications such as high performance imaging, optical projection, augmented/virtual reality, and miniaturized m…
To What Extent Can Space Be Compressed? Bandwidth Limits of Spaceplates
Kunal Shastri, Orad Reshef, Robert W. Boyd +2
Spaceplates are novel flat-optic devices that implement the optical response of a free-space volume over a smaller length, effectively "compressing space" for light propagation. To…
Emulating exceptional-point encirclements using imperfect (leaky) photonic components
J. B. Khurgin, Y. Sebbag, E. Edrei +4
Non-Hermitian systems have recently attracted significant attention in photonics. One of the hallmarks of these systems is the possibility of realizing asymmetric mode switching an…
Dissipation-induced topological transitions in continuous Weyl materials
Kunal Shastri, Francesco Monticone
Many topologically non-trivial systems have been recently realized using electromagnetic, acoustic, and other classical wave-based platforms. As the simplest class of three-dimensi…
Unidirectional and diffractionless surface plasmon-polaritons on three-dimensional nonreciprocal plasmonic platforms
S. Ali Hassani Gangaraj, George W. Hanson, Mario G. Silveirinha +3
Light-matter interactions in conventional nanophotonic structures typically lack directionality. Furthermore, surface waves supported by conventional material substrates do not usu…
