Dual-polarization control of broadband nonreciprocal thermal radiation by combining local and nonlocal metasurfaces
Shuang Xia, Mengqi Liu, Wenjian Wan +10
Nonreciprocal thermal radiation offers a route to decouple spectral directional absorptivity and emissivity, thereby enabling new paradigms in thermal-photonic systems. However, in…
Correlating Quasi-Optical Coupling Efficiency with Measured Receiver Noise Temperature in Metalens Coupled THz HEB Mixer
Jingqi Hu, Rui Wang, Jiameng Wang +3
Quasi-optical coupling serves as the critical interface in terahertz (THz) heterodyne receiver systems, enabling efficient transfer of incident radiation to photomixers through a f…
Terahertz semiconductor laser chaos
Binbin Liu, Carlo Silvestri, Kang Zhou +12
Chaos characterized by its irregularity and high sensitivity to initial conditions finds various applications in secure optical communications, random number generations, light det…
Farey tree locking of terahertz semiconductor laser frequency combs
Guibin Liu, Xuhong Ma, Kang Zhou +12
Frequency combs show various applications in molecular fingerprinting, imaging, communications, and so on. In the terahertz frequency range, semiconductor-based quantum cascade las…
