Adapting terahertz spintronic emitters towards maximum performance

Pierre Koleják, Geoffrey Lezier, Lukáš Halagačka, Baptiste Mathmann, Daniel Vala, Zuzana Gelnárová, Yannick Dusch, Jean-François Lampin, Nicolas Tiercelin, Kamil Postava, Mathias Vanwolleghem

The boom in terahertz technologies of the last few decades is now not limited to the use of electric charge, but also fully exploits spin. Revolutionary spintronic terahertz emitters (STEs) offer versatile usage under a wide range of visible and infrared excitation wavelengths, arbitrary reflection…

Spintronic inverse spin hall photomixing beyond 1THz

Pierre Kolejak, Geoffrey Lezier, Guillaume Ducournau, Jean-Francois Lampin, Nicolas Tiercelin, Mathias Vanwolleghem

We have demonstrated experimentally how ultrabroadband inverse spin Hall emitters present an unprecedented new scheme for room temperature THz CW and frequency comb generation. Building on previous proof-of-principle demonstrations, we demonstrate here by improved experimental developments how this…

From Noise analysis to Error Bars on Refractive Index In THz-TDS

Noureddin Osseiran, Jeyan Bichon, Aditya Raj, Théo Hannotte, Sophie Eliet, Romain Peretti

We present a new methodology for computing error bars in THz-TDS experiments and distribute open source software for this purpose. Pursuing our efforts in noise analysis and data processing of THz-TDS experiments, we followed a standard approach to derive the error bars from the simplest quantities…

Low-loss, 1-m long length, hollow-core THz waveguide operating at 1 THz, based on anti-resonant guiding mechanism

Georges Humbert, Jean-Louis Auguste, Guillaume Ducournau, Jean-Francois Lampin

A hollow-core THz waveguide composed of 10 silica capillaries is designed and fabricated. The waveguide based on the anti-resonant guiding mechanism presents a large transmission window (∼>600 GHz) centered at 1 THz, with measured propagation losses below 0.5 dB/m.

Acousto-Optical Tunable Filter design for efficient diffraction of unpolarised light

Samuel Dupont, Jean-Claude Kastelik, J. Vanhamel, E. Dekemper

Diffraction of optical waves by an acoustic grating is a well-known phenomenon that enables the design of versatile devices useful in photonic systems. For example, acousto-optic tunable filters (AOTFs) can be dynamically tuned by radio-frequency signals. Among possible material choice,…

Design of a Radio Frequency Compensation System, using the Electrical Characterisation of a Multi-Transducer Acousto-Optical Tunable Filter

J. Vanhamel, Samuel Dupont, Jean-Claude Kastelik, E. Dekemper

Acousto-Optical Tunable Filters (AOTFs) make use of the interaction between sound and light. To generate an ultrasound diffraction grating, a Radio-Frequency (RF) signal is applied to a piezoelectric transducer. The optical pass band can be controlled by adapting the properties of this transducer…

Hyperuniform versus Poisson Distributions in Random Metasurfaces at Infrared Wavelengths

Eric Lheurette, Roman Buisine, Olivier Vanbesien, David Dereudre, Ludovic Burgnies, Thibault Deletang, Benoît Cluzel

In this communication, we compare the relevance of two kinds of random distributions of Metal Isolant Metal (MIM) resonators describing a metasurface for extinction of an impinging incident signal at infrared wavelengths. The patterns are generated by home-made codes prior to numerical simulations…
