Polarization control of emitted THz waves using spintronic emitters with anisotropic magnetic layers & birefringence characterization of Quartz

Geoffrey Lezier, Pierre Kolejak, Jean-Francois Lampin, Kamil Postava, Mathias Vanwolleghem, Nicolas Tiercelin

We demonstrate that spintronic TeraHertz emitters using uni-axial anisotropic FeCo/TbCo 2 /FeCo ferromagnetic layers allow the polarization control of the THz emitted wave thanks to the Stoner-Wohlfarth coherent rotation of magnetization when submitted to a magnetic field along hard axis. The...

THz s-SNOM imaging of logarithmic spiral antennas

C. Santos, Louis Thomas, Théo Hannotte, Melanie Lavancier, Sophie Eliet, Jean-Francois Lampin, Romain Peretti

Probing the near-field of photonic components at sub-wavelength scale is of high interest to improve the design of future THz devices. We report on the THz near-field imaging of logarithmic spiral antennas by scattering-type scanning near-field optical microscopy (s-SNOM). Our results demonstrate...

Beyond the Dynamic range approach In noise evaluation for Terahertz Time domain spectrometers

Clemence Muller, Melanie Lavancier, Jeyan Bichon, Theo Hannotte, Jean-Francois Lampin, Sophie Eliet, Romain Peretti

THz-TDS is used for a myriad of purposes. Still today, the usual way to compare different system in terms of signal to noise ratio is to look at the dynamic range. We propose here a more reliable method based on statistics and will show results on two systems (Toptica and Menlo).

Magneto-electric control of polarization in spintronic terahertz emitters

Nicolas Tiercelin, Geoffrey Lezier, Pierre Kolejak, Jean-Francois Lampin, Yannick Dusch, Kamil Postava, Mathias Vanwolleghem

Magnetoelectric control of the emitted polarization of THz waves was demonstrated for the first time in spintronic emitters thanks to the use of a magnetostrictive ferromagnetic layer in an emitter deposited on top of a ferroelectric relaxor substrate.
