Axion-Field-Enabled Nonreciprocal Thermal Radiation in Weyl Semimetals
Bo Zhao, Cheng Guo, Christina A. C. Garcia +2
Objects around us constantly emit and absorb thermal radiation. The emission and absorption processes are governed by two fundamental radiative properties: emissivity and absorptiv…
Nonreciprocal radiative heat transfer between two planar bodies
Lingling Fan, Yu Guo, Georgia T. Papadakis +5
We develop an analytical framework for nonreciprocal radiative heat transfer in two-body planar systems. Based on our formalism, we identify effects that are uniquely nonreciprocal…
-Symmetric Topological Edge-Gain Effect
Alex Y. Song, Xiao-Qi Sun, Avik Dutt +6
We demonstrate a non-Hermitian topological effect that is characterized by having complex eigenvalues only in the edge states of a topological material, despite the fact that the m…
Creating locally interacting Hamiltonians in the synthetic frequency dimension for photons
Luqi Yuan, Avik Dutt, Mingpu Qin +2
The recent emerging field of synthetic dimension in photonics offers a variety of opportunities for manipulating different internal degrees of freedom of photons such as the spectr…
Relation between Photon Thermal Hall Effect and Persistent Heat Current in Nonreciprocal Radiative Heat Transfer
Cheng Guo, Yu Guo, Shanhui Fan
We study the photon thermal Hall effect and the persistent heat current in radiative heat transfer. We show that the photon thermal Hall effect is not a uniquely nonreciprocal effe…
Broadening near-field emission for performance enhancement in thermophotovoltaics
Georgia T. Papadakis, Siddharth Buddhiraju, Zhexin Zhao +2
The conventional notion for achieving high efficiency in thermophotovoltaics (TPVs) is to use a monochromatic emission at a photon energy corresponding to the band gap of the cell.…
A single photonic cavity with two independent physical synthetic dimensions
Avik Dutt, Qian Lin, Luqi Yuan +3
The concept of synthetic dimensions, which has enabled the study of higher-dimensional physics on lower-dimensional physical structures, has generated significant recent interest i…
Forward-Mode Differentiation of Maxwell's Equations
Tyler W Hughes, Ian A D Williamson, Momchil Minkov +1
We present a previously unexplored forward-mode differentiation method for Maxwell's equations, with applications in the field of sensitivity analysis. This approach yields exact g…
Doubly-resonant nonlinear photonic crystal cavity based on a bound state in the continuum
Momchil Minkov, Dario Gerace, Shanhui Fan
Photonic nanostructures simultaneously maximizing spectral and spatial overlap between fundamental and second-harmonic confined modes are highly desirable for enhancing second-orde…
Photonic refrigeration from time-modulated thermal emission
Siddharth Buddhiraju, Wei Li, Shanhui Fan
Active photonic cooling is of significant importance to realize robust, compact, vibration-free, all-solid-state refrigeration. Currently proposed photonic cooling approaches are b…
Inverse-designed photonic circuits for fully passive, bias-free Kerr-based nonreciprocal transmission and routing
Ki Youl Yang, Jinhie Skarda, Michele Cotrufo +6
Nonreciprocal devices such as isolators and circulators are key enabling technologies for communication systems, both at microwave and optical frequencies. While nonreciprocal devi…
Overcoming the absorption limit in high-harmonic generation from crystals
Hanzhe Liu, Giulio Vampa, Jingyuan Linda Zhang +6
Since the new millennium coherent extreme ultra-violet and soft x-ray radiation has revolutionized the understanding of dynamical physical, chemical and biological systems at the e…
Meron Spin Textures in Momentum Space
Cheng Guo, Meng Xiao, Yu Guo +2
We reveal the meron and antimeron spin textures in momentum space in a photonic crystal slab. These spin textures in momentum space have not been previously noted either in electro…
Penetration depth reduction with plasmonic metafilms
Nathan Z. Zhao, Ian A. D. Williamson, Zhexin Zhao +2
In many optical systems, including metal films, dielectric reflectors, and photonic crystals, electromagnetic waves can experience evanescent decay. The spatial length scale of suc…
Experimental band structure spectroscopy along a synthetic dimension
Avik Dutt, Momchil Minkov, Qian Lin +3
In recent years there has been significant interest in the concepts of synthetic dimensions, where one couples the internal degrees of freedom of a particle to form higher-dimensio…
