Giant frequency-selective near-field energy transfer in active--passive structures
Chinmay Khandekar, Weiliang Jin, Owen D. Miller +2
We apply a fluctuation electrodynamics framework in combination with semianalytical (dipolar) approximations to study amplified spontaneous energy transfer (ASET) between active an…
Amplified and directional spontaneous emission from arbitrary composite bodies: self-consistent treatment of Purcell effect below threshold
Weiliang Jin, Chinmay Khandekar, Adi Pick +2
We study amplified spontaneous emission (ASE) from wavelength-scale composite bodies--complicated arrangements of active and passive media--demonstrating highly directional and tun…
Temperature control of thermal radiation from heterogeneous bodies
Weiliang Jin, Athanasios G. Polimeridis, Alejandro W. Rodriguez
We demonstrate that recent advances in nanoscale thermal transport and temperature manipulation can be brought to bear on the problem of tailoring thermal radiation from compact em…
Fluctuating volume-current formulation of electromagnetic fluctuations in inhomogeneous media: incandecence and luminescence in arbitrary geometries
Athanasios G. Polimeridis, M. T. Homer Reid, Weiliang Jin +3
We describe a fluctuating volume--current formulation of electromagnetic fluctuations that extends our recent work on heat exchange and Casimir interactions between arbitrarily sha…
