Detectorless 3D terahertz imaging: achieving subwavelength resolution with reflectance confocal interferometric microscopy
Jorge Silva, Martin Plöschner, Karl Bertling +18
Terahertz imaging holds great potential for non-destructive material inspection, but practical implementation has been limited by resolution constraints. In this study, we present…

Shaping terahertz harmonic frequency combs with frequency dependent external reflectors
Carlo Silvestri, Xiaoqiong Qi, Thomas Taimre +1
We present a method for engineering harmonic frequency combs (HFCs) in the terahertz spectral region. This approach involves interfacing a quantum cascade laser (QCL) with an exter…
