Coherent Perfect Absorption in Chaotic Optical Microresonators for Efficient Modal Control
Xuefeng Jiang, Shixiong Yin, Huanan Li +5
Non-Hermitian wave engineering has attracted a surge of interest in photonics in recent years. One of the prominent phenomena is coherent perfect absorption (CPA), in which the ann…
Temporal Parity-Time Symmetry for Extreme Energy Transformations
Huanan Li, Shixiong Yin, Emanuele Galiffi +1
Temporal interfaces introduced by abrupt switching of the constitutive parameters of unbounded media enable unusual wave phenomena. So far, their explorations have been mostly limi…
Implementation of Optimal Thermal Radiation Pumps using Adiabatically Modulated Photonic Cavities
Lucas J. Fernández-Alcázar, Huanan Li, Mona Nafari +1
We numerically implement the concept of thermal radiation pumps in realistic photonic circuits and demonstrate their efficiency to control the radiation current, emitted between tw…
Temporal Switching to Extend the Bandwidth of Thin Absorbers
Huanan Li, Andrea Alù
Wave absorption in time-invariant, passive thin films is fundamentally limited by a trade-off between bandwidth and overall thickness. In this work, we investigate the use of tempo…
Virtual Parity-Time Symmetry
Huanan Li, Ahmed Mekawy, Alex Krasnok +1
Parity-time (PT) symmetry has been opening exciting opportunities in optics, yet the required careful balance of loss and gain has been hindering its practical implementations. Her…
Theory and Design of Multifunctional Space-Time Metasurfaces
Xuchen Wang, Ana Diaz-Rubio, Huanan Li +2
Integrating multiple functionalities into a single metasurface is becoming of great interest for future intelligent communication systems. While such devices have been extensively…
