Nonreciprocal Infrared Absorption via Resonant Magneto-optical Coupling to InAs
Komron Shayegan, Bo Zhao, Yonghwi Kim +2
Nonreciprocal elements are a vital building block of electrical and optical systems. In the infrared regime, there is a particular interest in structures that break reciprocity bec…
Violating Kirchhoff's Law of Thermal Radiation in Semitransparent Structures
Yubin Park, Viktar S. Asadchy, Bo Zhao +3
Kirchhoff's law of thermal radiation imposes a constraint on photon-based energy harvesting processes since part of the incident energy flux is inevitably emitted back to the sourc…
High-Performance Photonic Transformers for DC Voltage Conversion
Bo Zhao, Sid Assawaworrarit, Parthiban Santhanam +2
Direct current (DC) converters play an essential role in electronic circuits. Conventional high-efficiency DC voltage converters, especially step-up type, rely on switch-mode opera…
Sub-Wavelength Passive Optical Isolators Using Photonic Structures Based on Weyl Semimetals
Viktar Asadchy, Cheng Guo, Bo Zhao +1
We design sub-wavelength high-performing non-reciprocal optical devices using recently discovered magnetic Weyl semimetals. These passive bulk topological materials exhibit anomalo…
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…
