An optics-free computational spectrometer using a broadband and tunable dynamic detector
Ling-Dong Kong, Qing-Yuan Zhao, Hui Wang +11
Optical spectrometers are the central instruments for exploring the interaction between light and matter. The current pursuit of the field is to design a spectrometer without the n…
Terahertz Nonlinear Superconducting Metamaterials
Caihong Zhang, Biaobing Jin, Jiaguang Han +7
We investigate the nonlinear effect of a planar superconducting metamaterial made from niobium nitride (NbN) at terahertz frequencies. As the variation of the incident intense tera…
High-Q terahertz metamaterial from superconducting niobium nitride films
C. H. Zhang, J. B. Wu, B. B. Jin +5
We present in this letter terahertz (THz) metamaterials with low ohmic losses made from low-temperature superconductor niobium nitride (NbN) films. The resonance properties are cha…
Low Loss and Magnetic Field-tuned Superconducting THz Metamaterial
Biaobing Jin, Caihong Zhang, Sebastian Engelbrecht +8
Superconducting terahertz (THz) metamaterial (MM) made from superconducting Nb film has been investigated using a continuous-wave THz spectroscopy with a superconducting split-coil…
