Environment-Aware Channel Measurement and Modeling for Terahertz Monostatic Sensing
Integrated sensing and communication (ISAC) at terahertz (THz) frequencies holds significant promise for unifying ultra-high-speed wireless connectivity with fine-grained environmental awareness. Realistic and interpretable channel modeling is essential to fully realize the potential of such systems. This work presents a comprehensive investigation of monostatic sensing channels at 300~GHz, based on an extensive measurement campaign conducted at 57 co-located transceiver (TRx) positions across …

Giant enhancement of terahertz high-harmonic generation by cavity engineering of Dirac semimetal
Engineered micro- or nano-structures based on nonlinear optical materials offer versatile opportunities for optoelectronic applications. While extensive efforts have been devoted to design tailored microcavities to promote and increase the optical nonlinearities of graphene, the potential of engineering its three-dimensional counterparts -- three-dimensional Dirac semimetals -- remains largely unexplored. Here we report on exceptionally strong terahertz nonlinearities in a cavity-engineered Dir…

A quest for sulfur-bearing refractory species. Identification of CaS in the interstellar medium
The recent detection of refractory molecules in massive star-forming regions provides a means of probing the innermost regions of disks around massive stars. These detections also make it possible to explore the chemical composition of refractories through gas-phase observations. In this regard, identifying refractory compounds containing sulfur could reveal potential connections between sulfur and refractories, as well as help determine the sulfur budget in these extreme environments. We find …

Terahertz Chiral Optics with Ordered Carbon Nanotube Architectures
Chiral optical terahertz (THz) devices have significant technological implications for telecommunications, spectroscopy, and sensing. Engineering tunable, broadband, and cost-effective THz chiral materials has long been recognized as a challenging endeavor and has been the bottleneck hindering the full exploitation of the THz spectrum. Here, we present an artificial structure based on aligned carbon nanotube films that exhibit a tunable broadband circular dichroism (CD) up to 2.8 degrees. Its b…

Deterministic single-photon source over the terahertz regime
We propose a deterministic single-photon source in the terahertz (THz) regime, triggered by a sequence of coherent optical pulses. The scheme leverages the permanent dipole moment of a single-polar quantum emitter to induce THz transitions between optically dressed states, enhanced by a resonant coupling to a hybrid THz cavity. We present a cavity design that delivers high efficiency, purity, and indistinguishability while also enabling easy tunability of the emission frequency across the THz r…

Inverse-Designed On-Chip Terahertz Three-Channel Mode and Wavelength Division Demultiplexer
High-performance multimode/multiwavelength (de)multiplexer is one of the most pivotal photonic devices for advanced on-chip interconnect systems. Traditional on-chip photonic (de)multiplexing requires large device footprint for maintaining high efficiency, large operation bandwidth, and small insertion losses. Here a hybrid inverse design method is therefore proposed to combine genetic algorithms (GA) and topology optimization for developing an ultracompact (lateral size< 2λ) terahertz (THz) m…
