Arbitrary-order exceptional points in a nanomechanical cavity
Ning Wu, Kaiyu Cui, Ziming Chen +7
Higher-order exceptional points (EPs) govern non-Hermitian system dynamics through their enriched and sharpened spectral topology, yet the intrinsic topological fragility hinders r…
Multi-channel electrically tunable varifocal metalens with compact multilayer polarization-dependent metasurfaces and liquid crystals
Zhiyao Ma, Zhe Li, Tian Tian +8
As an essential module of optical systems, varifocal lens usually consists of multiple mechanically moving lenses along the optical axis. The recent development of metasurfaces wit…
SUANPAN: Scalable Photonic Linear Vector Machine
Ziyue Yang, Chen Li, Yuqia Ran +12
Photonic linear operation is a promising approach to handle the extensive vector multiplications in artificial intelligence techniques due to the natural bosonic parallelism and hi…
Electrically switchable -channel wave-front control with N cascaded polarization-dependent metasurfaces
Zhiyao Ma, Tian Tian, Yuxuan Liao +7
Metasurfaces with tunable functionalities are greatly desired for modern optical system and various applications. To increase the operating channels of polarization-multiplexed met…
