Reconstruction of partially occluded objects with a physics-driven self-training neural network
Mingjun Xiang, Kai Zhou, Hui Yuan +1
This study proposes a novel approach utilizing a physics-informed deep learning (DL) algorithm to reconstruct occluded objects in a terahertz (THz) holographic system. Taking the a…
Strong coupling of plasmonic bright and dark modes with two eigenmodes of a photonic crystal cavity
Fanqi Meng, Lei Cao, Aristeidis Karalis +3
Dark modes represent a class of forbidden transitions or transitions with weak dipole moments between energy states. Due to their low transition probability, it is difficult to rea…
600-GHz Fourier Imaging Based on Heterodyne Detection at the 2nd Sub-harmonic
Hui Yuan, Alvydas Lisauskas, Mark D. Thomson +1
Fourier imaging is an indirect imaging method which records the diffraction pattern of the object scene coherently in the focal plane of the imaging system and reconstructs the ima…
Higher-harmonic generation in boron-doped silicon from band carriers and bound-dopant photoionization
Fanqi Meng, Frederik Walla, Sergey Kovalev +10
We investigate ultrafast harmonic generation (HG) in Si:B, driven by intense pump pulses with fields reaching ~100 kV/cm and a carrier frequency of 300 GHz, at 4 K and 300 K, both…
Amplitude/Phase Retrieval for Terahertz Holography with Supervised and Unsupervised Physics-Informed Deep Learning
Mingjun Xiang, Hui Yuan, Lingxiao Wang +2
Recently, digital holographic imaging techniques (including methods with heterodyne detection) have found increased attention in the terahertz (THz) frequency range. However, holog…
Determination of the Carrier-Envelope Phase of Few-Cycle Laser Pulses with Terahertz-Emission Spectroscopy
Markus Kress, Torsten Loeffler, Mark D. Thomson +8
The availability of few-cycle optical pulses opens a window to physical phenomena occurring on the attosecond time scale. In order to take full advantage of such pulses, it is cruc…
