Observation of enhanced free-electron radiation from photonic flatband resonances
Yi Yang, Charles Roques-Carmes, Steven E. Kooi +6
Flatbands emerge from a myriad of structures such as Landau levels, Lieb and Kagome lattices, linegraphs, and more recently moire superlattices. They enable unique properties inclu…
Momentum considerations inside near-zero index materials
Michaël Lobet, Iñigo Liberal, Larissa Vertchenko +3
Near-zero-index (NZI) materials, i.e. materials having a phase refractive index close to zero, are known to enhance or inhibit light-matter interactions. Most theoretical derivatio…
Genetic-algorithm-aided ultra-broadband perfect absorbers using plasmonic metamaterials
Alexandre Mayer, Hai Bi, Sarah Griesse-Nascimento +5
Complete absorption of electromagnetic waves is paramount in today's applications, ranging from photovoltaics to cross-talk prevention into sensitive devices. In this context, we u…
Modeling the optical properties of Twisted Bilayer Photonic Crystals
Haoning Tang, Fan Du, Stephen Carr +3
We demonstrate a photonic analog of twisted bilayer graphene that has ultra-flat photonic bands and exhibits extreme slow light behavior. Our twisted bilayer photonic device, which…
Relaxed phase-matching constraints in zero-index waveguides
Justin R. Gagnon, Orad Reshef, Daniel H. G. Espinosa +8
The nonlinear optical response of materials is the foundation upon which applications such as frequency conversion, all-optical signal processing, molecular spectroscopy, and nonli…
