Temporal Fourier Optics Reveals Hidden Hybridized Light-Matter States
Juan-Feng Zhu, Wenjie Zhou, Shihao Feng +5
Spectral measurements provide fundamental insights into wave systems by revealing resonances, mode hybridization, and light-matter interactions. However, intrinsic dissipation and…
Observation of the Inherent Chiral Smith-Purcell Effect via Symmetry Breaking
Juan-Feng Zhu, Fei Chen, Jun-Xuan Chen +9
The Smith-Purcell effect arises when charged particles move near a periodic structure, emitting radiation. Conventional approaches for generating chiral Smith-Purcell radiation rel…
Spectral localization of single-nanoparticle plasmons through photonic substrate engineering
Shihao Feng, Juan-Feng Zhu, Xinyi Fan +8
Surface plasmon resonances (SPRs) are crucial for confining light beyond the diffraction limit, yet heavy metal losses often limit their spectral localization. Here, we propose a p…
Probing dynamics of time-varying media: Beyond abrupt temporal interfaces
Ayan Nussupbekov, Juan-Feng Zhu, Yuriy Akimov +4
This work investigates the effects of time-varying media, where optical properties change over time, on electromagnetic wave propagation, focusing on plane waves and free-electron…
