Near-field refrigeration and tunable heat exchange through four-wave mixing
Chinmay Khandekar, Riccardo Messina, Alejandro W. Rodriguez
We modify and extend a recently proposed four-wave mixing scheme [Opt. Express 25 (19),23164 (2017)] for achieving near-field thermal upconversion and energy transfer, to demonstra…
Inverse designed photonic fibers and metasurfaces for nonlinear frequency conversion
Chawin Sitawarin, Weiliang Jin, Zin Lin +1
Typically, photonic waveguides designed for nonlinear frequency conversion rely on intuitive and established principles, including index guiding and band gap engineering, and are b…
Photon Torpedoes and Rytov Pinwheels: Integral-Equation Modeling of Non-Equilibrium Fluctuation-Induced Forces and Torques on Nanoparticles
M. T. Homer Reid, O. D. Miller, A. G. Polimeridis +3
We present new theoretical tools, based on fluctuational electrodynamics and the integral-equation approach to computational electromagnetism, for numerical modeling of forces and…
Topology Optimized Multi-layered Meta-optics
Zin Lin, Benedikt Groever, Federico Capasso +2
We propose a general topology optimization framework for metasurface inverse design that can automatically discover highly complex multi-layered meta-structures with increased func…
Enhanced nonlinear frequency conversion and Purcell enhancement at exceptional points
Adi Pick, Zin Lin, Weiliang Jin +1
We derive analytical formulas quantifying radiative emission from subwavelength emitters embedded in triply resonant nonlinear cavities supporting exceptional points (EP)…
Ballistic near-field heat transport in dense many-body systems
Ivan Latella, Svend-Age Biehs, Riccardo Messina +2
Radiative heat-transport mediated by near-field interactions is known to be superdiffusive in dilute, many-body systems. In this Letter we use a generalized Landauer theory of radi…
