Electrical and radiation characteristics of semilarge photoconductive terahertz emitters [PDF]
, 2004 We present experimental characterization of semilarge photoconductive emitters, including their electrical/photoconductive parameters and terahertz spectra. A range of emitters were studied and fabricated on both LT-GaAs and SI-GaAs, having a variety

Terahertz range quantum well infrared photodetector [PDF]
Applied Physics Letters, 2004 We demonstrated a GaAs/AlGaAs-based far-infrared quantum well infrared photodetector at a wavelength of λ=84 μm. The relevant intersubband transition is slightly diagonal with a dipole matrix element of 3.0 nm. At 10 K, a responsivity of 8.6 mA/W and a detectivity of 5×107 cm √Hz/W have been achieved; and successful detection up to a device temperature

Time domain terahertz impulse ranging studies [PDF]
Applied Physics Letters, 1995 We present time domain impulse scattering measurements of freely propagating terahertz radiation measured with subpicosecond resolution. This fast time response corresponds to a usable bandwidth of over 1 THz. Measured scattered fields from thin wire targets agree well with the calculated scattering for the early and late time response in both the time
