Transport-defined photodetection through electrically selectable nonequilibrium carrier transport
Jiaxuan Cai, Yan Xie, Ning Yang +9
Broadband optical fields can change in both intensity and spectral distribution, but a fixed-response detector maps this evolving information onto a single electrical signal. Here…
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…
Sculpting harmonic comb states in terahertz quantum cascade lasers by controlled engineering
Elisa Riccardi, M. Alejandro Justo Guerrero, Valentino Pistore +6
Optical frequency combs (FCs), that establish a rigid phase-coherent link between the microwave and optical domains of the electromagnetic spectrum, are emerging as a key high-prec…
Quantum Cascade Laser Based Hybrid Dual Comb Spectrometer
Luigi Consolino, Malik Nafa, Michele De Regis +9
Four-wave-mixing-based quantum cascade laser frequency combs (QCL-FC) are a powerful photonic tool, driving a recent revolution in major molecular fingerprint regions, i.e. mid- an…
Quasi-static and propagating modes in three-dimensional THz circuits
Mathieu Jeannin, Djamal Gacemi, Angela Vasanelli +6
We provide an analysis of the electromagnetic modes of three-dimensional metamaterial resonators in the THz frequency range. The fundamental resonance of the structures is fully de…
Fully phase-stabilized quantum cascade laser frequency comb
Luigi Consolino, Malik Nafa, Francesco Cappelli +8
Optical frequency comb synthesizers (FCs) [1] are laser sources covering a broad spectral range with a number of discrete, equally spaced and highly coherent frequency components,…
