We investigate ultrafast harmonic generation (HG) in Si:B, driven by intense pump pulses with fields reaching ∼100kVcm^{−1} and a carrier frequency of 300 GHz, at 4 K and 300 K, both experimentally and theoretically. We report several findings co

We investigate the coherent coupling of metamaterial resonators with hydrogen-like boron acceptors in Si at cryogenic temperatures. When the resonance frequency of the metamaterial, chosen to be in the range 7–9 THz, superimposes the transition fre

We observe third-harmonic generation (THG) and fifth-harmonic generation (FHG) of free holes in the valence band of bulk Si:B at cryogenic temperature upon irradiation with intense terahertz pulses from a free-electron laser, polarized along the Γ

We demonstrate the use of spectrograms of the field-induced second-harmonic (FISH) signal generated in ambient air, to reconstruct the absolute temporal electric field of ultra-broadband terahertz-infrared (THz-IR) pulses with bandwidths exceeding 10

We report high-harmonic generation up to the ninth order from boron-doped Si at room temperature, pumped by intense THz pulses. For comparison with the experiment, we also performed FDTD simulations coupled to a full-band Monte Carlo device model. Th

We observe third-harmonic generation (THG) and fifth-harmonic generation (FHG) of terahertz free-electron laser (FEL) pulses in Si:B at cryogenic temperatures. The intensities of the harmonics increase as a function of pulse energy following power la
