Design of a low-loss hybrid silicon-organic terahertz field detector

We propose an innovative design for an integrated, low-loss on-chip terahertz (THz) field detector based on hybrid silicon-organic slot waveguides and THz antennas.

Simultaneous Multi-Target Monitoring with Terahertz Leaky-Wave Radar

Leaky-wave radar has emerged as a viable alternative to mechanically steered terahertz radar systems. This technique is enabled by the relationship between angle-of-arrival and frequency, allowing the both the range and angle information of a target to ...

Power scaling of ultra-thin terahertz beam-splitters

, 2012
Extent: 2p.A low-cost ultra-thin broadband terahertz beam-splitter based on a thin conductive layer has previously been fabricated and tested. Here, this paper shows the linearity of power scaling of the beam-splitter from lower to higher power in ...

Application of terahertz spectroscopy to the characterization of biological samples using birefringence silicon grating [PDF]

, 2012
We present a device and method for performing vector transmission spectroscopy on biological specimens at terahertz (THz) frequencies. The device consists of artificial dielectric birefringence obtained from silicon microfluidic grating structures. The

Terahertz Direct Detection in YBa2Cu3O7 Microbolometers

, 2011
A high sensitivity broadband terahertz direct detector based on YBa2Cu3O7 high-Tc superconductor microbolometers is presented. At 77 K, the responsivity of the spiral antenna-integrated microbolometers (1.5 um x 1.5 um) is 190 V/W, referenced to the ...

Real-Time Integrated Photonic Dehopping of Terahertz Frequency-Hopping Signals Around the 300 GHz Band Using Electro-Optically Tunable Lasers

Photonics
We propose and experimentally demonstrate an integrated photonic terahertz (THz) frequency-hopping (FH)/dehopping system using electro-optically wavelength-tunable lasers to enhance physical-layer security in terahertz wireless links.

Terahertz magnetic plasmon waveguides

, 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
