2D Plasmonics for Enabling Novel Light-Matter Interactions
Nicholas Rivera, Ido Kaminer, Bo Zhen +2
The physics of light-matter interactions is strongly constrained by both the small value of the fine-structure constant and the small size of the atom. Overcoming these limitations…
Broadband Angular Selectivity of Light at the Nanoscale: Progress, Applications and Outlook
Yichen Shen, Chia Wei Hsu, Yi Xiang Yeng +2
Humankind has long endeavored to control the propagation direction of light. Since time immemorial, shades, lenses and mirrors have been used to control the flow of light. In moder…
Substrate-Independent Light Confinement in Bioinspired All-Dielectric Surface Resonators
Emma C. Regan, Yichen Shen, Josue J. Lopez +4
Traditionally, photonic crystal slabs can support resonances that are strongly confined to the slab but also couple to external radiation. However, when a photonic crystal slab is…
Power--bandwidth limitations of an optical resonance
Owen D. Miller, Chia Wei Hsu, Emma Anquillare +3
We present shape-independent upper limits to the power--bandwidth product for a single resonance in an optical scatterer, with the bound depending only on the material susceptibili…
Efficient, designable, and broad-bandwidth optical extinction via aspect-ratio-tailored silver nanodisks
Emma L. Anquillare, Owen D. Miller, Chia Wei Hsu +4
Subwavelength resonators, ranging from single atoms to metallic nanoparticles, typically exhibit a narrow-bandwidth response to optical excitations. We computationally design and e…
An Invisible Metallic Mesh
Dexin Ye, Ling Lu, John D. Joannopoulos +2
We introduce a solid material that is itself invisible, possessing identical electromagnetic properties as air (i.e. not a cloak) at a desired frequency. Such a material could prov…
Dynamical Mechanism of Two-Dimensional Plasmon Launching by Swift Electrons
Xiao Lin, Xihang Shi, Fei Gao +8
Launching of surface plasmons by swift electrons has long been utilized in electron-energy-loss spectroscopy (EELS) to investigate plasmonic properties of ultrathin, or two-dimensi…
The Harper-Hofstadter Hamiltonian and conical diffraction in photonic lattices with grating assisted tunneling
Tena Dubček, Karlo Lelas, Dario Jukić +3
We introduce a grating assisted tunneling scheme for tunable synthetic magnetic fields in photonic lattices, which can be implemented at optical frequencies in optically induced on…
Spawning rings of exceptional points out of Dirac cones
Bo Zhen, Chia Wei Hsu, Yuichi Igarashi +6
The Dirac cone underlies many unique electronic properties of graphene and topological insulators, and its band structure--two conical bands touching at a single point--has also be…
Probing topological protection using a designer surface plasmon structure
Fei Gao, Zhen Gao, Xihang Shi +9
Topological photonic states, inspired by robust chiral edge states in topological insulators, have recently been demonstrated in a few photonic systems, including an array of coupl…
Experimental Observation of Large Chern numbers in Photonic Crystals
Scott A. Skirlo, Ling Lu, Qinghui Yan +3
Despite great interest in the quantum anomalous Hall phase and its analogs, all experimental studies in electronic and bosonic systems have been limited to a Chern number of one. H…
Fundamental limits to optical response in absorptive systems
Owen D. Miller, Athanasios G. Polimeridis, M. T. Homer Reid +5
At visible and infrared frequencies, metals show tantalizing promise for strong subwavelength resonances, but material loss typically dampens the response. We derive fundamental li…
