Performance of a compact, continuous-wave terahertz based on a quantum-cascade laser [PDF]

open access: yes, 2010
We report on the development of a compact, easy-to-use terahertz radiation source, which combines a quantum cascade laser (QCL) with a compact, low-input-power Stirling ...

An optically reconfigurable wideband frequency-selective rasorber/absorber at the THz band

open access: yesMaterials Research Express
Terahertz radar and antenna systems play a pivotal role in future communication and detection technologies. To realize in-band transmission and out-of-band absorption in terahertz radar and antenna systems, an optically reconfigurable wideband frequency ...

Terahertz magnetic plasmon waveguides

open access: yes, 2012
Extent: 2p.A design of subwavelength terahertz waveguides is presented in this manuscript. The structure is composed of a linear chain of split-ring resonators (SRRs), i.e., artificial magnetic atoms. The energy transport along the chain can be described

Nondestructive Inspection of Glass-Fiber Reinforced Plastic (GFRP) Composites with Photonic Terahertz Radar

open access: yes
We present high-resolution thickness measurement and volumetric imaging of multilayer glass fiber-reinforced plastics (GFRP) composites. For our investigations, we use a previously developed, broadband terahertz photonic frequency-modulated continuous ...

3D-Printed Quasi-Optics for Sub-Terahertz Range

open access: yes
The high bandwidth available in the terahertz domain is promising for non-destructive evaluation (NDE) and inspection applications. Although 3D-printing offers great flexibility and fast design iteration when developing quasi-optical components for such ...

Terahertz Squint SAR Imaging Based on Decoupled Frequency Scaling Algorithm

open access: yesRemote Sensing
Terahertz synthetic aperture radar (SAR) can achieve high-resolution imaging of the target area through a large bandwidth, while squint imaging can flexibly detect the target area by adjusting the beam direction.

Polarization variable terahertz metasurface along the propagation path

open access: yesFundamental Research
Conventional metasurfaces for terahertz polarization are limited to performing lateral (in the x-y plane) polarization control of the output wave. In such cases, the polarization state remains unchanged in each output plane along the propagation path ...

Flexible terahertz beam manipulation and convolution operations in light-controllable digital coding metasurfaces

open access: yesiScience
Summary: The development of coding metasurface opens an important development direction for beam modulator components. However, the lack of dynamic tunability is a major obstacle to the development and practicality of terahertz coding metasurface.

Measurements of the time-jitter of coherent terahertz synchrotron radiation with a superconducting detector [PDF]

open access: yes, 2012
We have applied an ultrafast superconducting YBa2Cu3O7-δ (YBCO) detector to study the time jitter of the propagating electron bunches in a synchrotron. The jitter was determined from the coherent terahertz (THz) synchrotron radiation (CSR)
