All-silicon terahertz components towards efficient integrated systems

open access: yes, 2020
Efficient integrated systems can be considered as a next milestone for practical applications of terahertz technology. Various types of integrated platforms have been directly scaled from either the microwave or optical domain, with benefits and ...

Laser‐Induced Ultrafast Magnetic Phase Transition in 2D Van Der Waals Antiferromagnetic Heterostructures

open access: yesAdvanced Science, EarlyView.
In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (

A micromechanical beam-steering device for terahertz systems [PDF]

open access: yes, 2004
Beam-steering techniques are required to fully exploit terahertz imaging systems. We propose and model a device employing artificial dielectric techniques to provide a variable phase-control medium.

Terahertz-Nanoscale Visualization of the Microscopic Spin-Charge Architecture of Colossal Magnetoresistive Switching. [PDF]

open access: yesAdv Sci (Weinh)
This study employs cryogenic magneto‐terahertz nanoscopy to reveal the real‐space electrodynamics of the colossal magnetoresistance transition. By capturing the terahertz electrodynamic evolution of field‐driven spin switching, the work unveils the dissipative dynamics of emergent metallic states, providing a high‐frequency view of coupled spin‐charge ...

Coherent two-dimensional terahertz-terahertz-Raman spectroscopy [PDF]

open access: yesProceedings of the National Academy of Sciences, 2016
Significance The thermally populated motions of liquids, including hydrogen bonds, low-energy bending vibrations, conformational torsions, and hindered rotations, are resonant in the terahertz region of the spectrum. These motions regulate solvation, macromolecular structure, and vibrational energy flow in liquid-phase chemistry.

Type‐II Dirac Fermions in Monolayer In2O: Interplay of Magnetotransport, Spin Hall Effect, and Superconductivity

open access: yesAdvanced Science, EarlyView.
First‐principles calculations reveal that monolayer In2O${\rm In}_2{\rm O}$ hosts type‐II Dirac fermions near the Fermi level, which split into Weyl points under spin‐orbit coupling. The material exhibits negative and giant magnetoresistance, a pronounced spin Hall effect, and phonon‐mediated superconductivity at 1.5 K, establishing it as a unique ...

Light-guiding-light-based temporal integration of broadband terahertz pulses in air

open access: yesAPL Photonics, 2023
The next generation of all-optical computation platforms prefers the light-guiding-light (LGL) scheme inside a medium that envisions circuitry-free and rapidly reconfigurable systems powered by dynamic interactions between light beams.

Terahertz Waveguide Prism

open access: yesAdvanced Photonics 2013, 2013
We present an easily fabricated waveguide prism for the terahertz (THz) frequency range. The prism is made of polypropylene and uses waveguide dispersion to spatially separate frequencies over the range of 0.1 to 0.7 THz. The diffraction properties of the prism were determined using electromagnetic field simulations and the waveguide parameters were ...

Broadband and efficient terahertz beam scanning using a 3D-printed Risley prism

open access: yes, 2022
We present a Risley prism beam-scanning system for terahertz waves. The scanning system consists of two 3Dprinted prisms made of cyclic olefin copolymer (COC), which is a low loss material at terahertz frequencies.

Two‐Dimensional Triferroics: From Fundamental Couplings to Multifunctional Applications

open access: yesAdvanced Science, EarlyView.
This graphic summarizes the three main types of currently reported 2D triferroic couplings. From the structural perspective, existing systems can be broadly classified into two categories, which exhibit distinct symmetry features and coupling behaviors. Beyond the lattice difference, a third type involves the interplay among ferroelectricity, magnetism,
