Optically locked low-noise photonic microwave oscillator
Zexing Zhao, Bin Li, Kunpeng Jia +13
The next-generation sensing and communication applications rely on high-frequency microwave generation with low-noise. The microwave photonic technology is promising by the practic…
Experimental signature of transient symmetry breaking in a cavity superconductor
Siyu Duan, Jingbo Wu, Xiaoqing Jia +5
Transient states of matter far from equilibrium may exhibit physical properties beyond those allowed by the equilibrium-state crystalline symmetries. We explore ultrafast and direc…
High-gain optical parametric amplification with a continuous-wave pump using a domain-engineered thin-film lithium niobate waveguide
Mengwen Chen, Chenyu Wang, Kunpeng Jia +16
While thin film lithium niobate (TFLN) is known for efficient signal generation, on-chip signal amplification remains challenging from fully integrated optical communication circui…
Hallmarks of terahertz magnon currents in an antiferromagnetic insulator
Hongsong Qiu, Oliver Franke, Yuanzhe Tian +11
The efficient transport of spin angular momentum is expected to play a crucial role in future spintronic devices, which potentially operate at frequencies reaching the terahertz ra…
