Ultrafast broadband circular dichroism in the deep ultraviolet

Majed Chergui, Thomas Charles Henry Rossi, Malte Oppermann, Benjamin Bauer, Jérôme Lacour

The measurement of chirality and its temporal evolution are crucial for the understanding of a large range of biological functions and chemical reactions. Steady-state circular dichroism (CD) is a standard analytical tool for measuring chirality in chemist ...

Terahertz Quarter Wave-Plate Metasurface Polarizer Based on Arrays of Graphene Ribbons

Babak Rahmani

We propose a novel graphene-dielectric-based meta-surface for manipulating the polarization of the incident light in the terahertz regime. The proposed structure comprised two orthogonally oriented periodic array of graphene ribbons (PAGRs) which are separ ...

Acoustic birefringence via non-Eulerian metamaterials

Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad

The recently proposed concept of metamaterials has opened exciting venues to control wave-matter interactions in unprecedented ways. Here, we demonstrate the relevance of metamaterials for inducing acoustic birefringence, a phenomenon which has already fou ...

Load-strengthening versus load-weakening faulting in gouge-bearing faults: insights from triaxial saw-cut experiments

Marie Estelle Solange Violay, Carolina Giorgetti, Iskander Louhichi

Brittle reactivation of pre-existing faults is theoretically constrained by their friction, the stress field orientation, and magnitude. Thus, following the Mohr-Coulomb failure criterion, the increase in tectonic shear stress leads to the reactivation of ...

Discrimination of temperature and strain by combined refractive index and birefringence measurements using coherent Rayleigh sensing

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Xin Lu

Temperature and strain discrimination is experimentally demonstrated in an elliptical-core polarization-maintaining fiber by making use of Rayleigh-based distributed birefringence measurements and the frequency shift of the correlation peak obtained by sta ...

Highly-sensitive distributed birefringence measurements based on a two-pulse interrogation of a dynamic Brillouin grating

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Andrey Denisov

A method for distributed birefringence measurements is proposed based on the interference pattern generated by the interrogation of a dynamic Brillouin grating (DBG) using two short consecutive optical pulses. Compared to existing DBG interrogation techniq ...

Fourier transform spectroscopy in the vibrational fingerprint region with a birefringent interferometer

Christoph Peter Hauri

We introduce a birefringent interferometer for Fourier transform (FT) spectroscopy in the mid-infrared, covering the vibrational fingerprint region (5-10 µm, 1000-2000 cm-1), which is crucial for molecular identification. Our interferometer empl ...

Femtosecond laser direct-write waveplates based on stress-induced birefringence

Yves Bellouard, Christos Edouardos Athanasiou

The use of femtosecond lasers to introduce controlled stress states has recently been demonstrated in silica glass. We use this technique, in combination with chemical etching, to generate and control stress-induced birefringence over a well-defined region ...
