Summary: Recent developments in nanomagnetism and spintronics have enabled the use of ultrafast spin physics for terahertz (THz) emission. Spintronic THz emitters, consisting of ferromagnetic (FM)/non-magnetic (NM) thin film heterostructures, have de

We report the conception, fabrication and characterization of a radar cross section reducing (RCSR) metasurface and its integration into a mesoscopic micromirror-array for terahertz spatial light modulation. The metasurface reduces the specular refle

Spintronic ferromagnetic/non-magnetic heterostructures are novel sources for the generation of THz radiation based on spin-to-charge conversion in the layers. The key technological and scientific challenge of THz spintronic emitters is to increase th

We present a terahertz-SLM with a frequency working range from 1.0 THz to 2.3 THz. Over the complete frequency range, the spatial modulation contrast exceeds 50% with a peak modulation contrast of 87% at 1.38 THz. The pixels of the SLM consist of mir

A spintronic bilayer structure of 2-nm Fe and 3-nm Pt was fabricated by molecular beam epitaxy on a Silicon substrate. We demonstrate that this Fe/Pt on Si heterostructure is an efficient and convenient alternative terahertz emitter particularly for

We present a new type of terahertz spatial light modulator (THz-SLM) based on an array of large micromirrors. The electrostatically tunable micromirrors spatially modulate terahertz waves in a frequency range from 0.97 THz to 2.28 THz with a peak mod

Recent studies in spintronics have highlighted ultrathin magnetic metallic multilayers as a novel and very promising class of broadband terahertz radiation sources. Such spintronic multilayers consist of ferromagnetic (FM) and non-magnetic (NM) thin
