Universal spin-resolved thermal radiation laws for nonreciprocal bianisotropic media
Chinmay Khandekar, Farhad Khosravi, Zhou Li +1
A chiral absorber of light can emit spin-polarized (circularly polarized) thermal radiation based on Kirchhoff's law which equates spin-resolved emissivity with spin-resolved absor…
Spectral domain inverse design for accelerating nanocomposite metamaterials discovery
Ashwin K. Boddeti, Abubakr Alabassi, Vaneet Aggarwal +1
Inverse design techniques in the context of nanophotonics have helped in discovery of compact and counter-intuitive structures/shapes. We introduce the concept of spectral domain i…
Switching dynamics of dark-pulse Kerr comb states in optical microresonators
Elham Nazemosadat, Attila Fülöp, Óskar B. Helgason +7
Dissipative Kerr solitons are localized structures that exist in optical microresonators. They lead to the formation of microcombs --- chip-scale frequency combs that could facilit…
Machine-Learning-Assisted Metasurface Design for High-Efficiency Thermal Emitter Optimization
Zhaxylyk A. Kudyshev, Alexander V. Kildishev, Vladimir M. Shalaev +1
With the emergence of new photonic and plasmonic materials with optimized properties as well as advanced nanofabrication techniques, nanophotonic devices are now capable of providi…
Quantum nonlinear mixing of thermal photons to surpass the blackbody limit
Chinmay Khandekar, Liping Yang, Alejandro W. Rodriguez +1
Nearly all thermal radiation phenomena involving materials with linear response can be accurately described via semi-classical theories of light. Here, we go beyond these tradition…
Negative refraction in time-varying, strongly-coupled plasmonic antenna-ENZ systems
V. Bruno, C. DeVault, S. Vezzoli +14
Time-varying metasurfaces are emerging as a powerful instrument for the dynamical control of the electromagnetic properties of a propagating wave. Here we demonstrate an efficient…
