Shadow-Free Scattering with Complex Frequency Excitations
Vitali Kozlov, Wei Wang, Seunghwi Kim +2
The optical theorem dictates that the wave scattering of an object in the forward direction is proportional to the total power extinguished from the excitation. For passive objects…
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…
Million-Q Free Space Meta-Optical Resonator at Visible Wavelengths
Jie Fang, Rui Chen, David Sharp +13
High-quality (Q)-factor optical resonators with extreme temporal coherence are of both technological and fundamental importance in optical metrology, continuous-wave lasing, and se…
Observation of Photonic Chiral Flatbands
Minho Choi, Andrea Alù, Arka Majumdar
Distinct selectivity to the spin angular momenta of photons have garnered significant attention in recent years, for their relevance in basic science and for imaging and sensing ap…
