Organic crystals with second-order optical nonlinearity feature very high and ultra-fast
optical nonlinearities and are therefore attractive for various photonics applications. During …

Lack of efficient routes to modulate the propagation properties of the terahertz (THz) wave is
a major barrier for the further development of THz technology. In recent years, two …

Due to the shape diversity and the occlusion problem, non-invasive inspection of cultural
relic with special-shaped structures has always been the bottleneck of the existing imaging …

Absorption spectra of explosives such as hexahydro-1, 3, 5-trinitro-1, 3, 5-triazine (RDX),
pentaerythritol tetranitrate (PETN), and mixtures of both were measured by terahertz time …

One of the most prominent applications of terahertz time-domain spectroscopy is the spectral
investigation of materials covered by visibly opaque objects. Therefore, terahertz waves are …

Low efficiency of the standard THz TDS method of the detection and identification of
substances based on a comparison of the spectrum for the signal under investigation with a …

The identification of various substances by multivariate data analysis of terahertz
transmittance spectra is demonstrated. Transmittance spectra were obtained by the use of a …

Low cost, low power consumption and high performance are urgent needs for the
application of terahertz modulation devices in the 6G field. Rhenium disulfide (ReS2) is one …

We report enhanced broadband terahertz (THz) generation and detailed characterization
from the interaction of femtosecond two-colour laser pulses with thin transparent dielectric …

We demonstrate principal limitations of standard Time Domain Spectroscopy based on a
broadband THz pulse for the detection and identification of substance using paper napkins …
