Transient Chirp Dynamics in Terahertz Quantum Cascade Lasers
Xianglong Bi, Xuhong Ma, Wenjian Wan +9
Laser frequency chirp is a ubiquitous dynamical process in semiconductor lasers, vital for frequency-modulated photonic systems. In the mid-infrared (MIR) and terahertz (THz) range…
Reconfigurable Terahertz Multi-Harmonic Dual-Combs
Ma Xuhong, Qin Zhiwei, Bi Xianglong +7
Dual-comb spectroscopy, constructed from two frequency combs with slightly different repetition frequencies, enables real-time and high-precision measurements without mechanical sc…
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…
