A generalized Kirchhoff's law of thermal radiation for Floquet media
Sander A. Mann, Dimitrios L. Sounas, Andrea Alù
Kirchhoff's law fundamentally relates thermal emission to absorption. For linear, static, reciprocal media, it equates the emissivity and absorptivity for each direction and freque…
Revealing Sharp Spectral Features with Complex Frequency Excitations: Challenges and Opportunities
Jacob B Khurgin, Andrea Alu, Vitaly Kozlov +1
Broadening of spectral and spatial responses due to intrinsic loss in real materials often hides sharp features. One recently recognized route to recover those features is to probe…
Optical Modulation Due to Energy Exchange Between Photonic and Exciton Modes in the Intermediate Coupling Regime
Evripidis Michail, Sander A. Mann, Kamyar Rashidi +4
Actively tunable photonic devices are vital for next-generation optoelectronics requiring rapid switching and high bandwidth. Although organic optoelectronic devices have found wid…
Microwave-to-optical transduction using magnon-exciton coupling in a layered antiferromagnet
Pratap Chandra Adak, Iris McDaniel, Suvodeep Paul +12
Coherent interfaces between microwave-frequency quantum systems and low-loss optical links are essential for quantum networks. However, existing microwave-optical transducers often…
Nonreciprocity in Quantum Technology
Shabir Barzanjeh, André Xuereb, Andrea Alù +4
Nonreciprocity-the ability to transmit signals in one direction while blocking them in the reverse-has become a powerful resource in quantum technologies, enabling directional ampl…
