Narrowband Optical Coupler Using Fano Interference in First Order Diffraction

Olivier Martin, Benjamin Gallinet, Giorgio Quaranta, Fabian Michael Lütolf

Light coupling in waveguides has been extensively investigated in a variety of contexts, from photonic integrated circuits to biosensing and near-eye displays for augmented reality. Here, narrowband diffraction is reported using a Fano interference effect ...

Extreme polarization-dependent supercontinuum generation in an uncladded silicon nitride waveguide

Camille Sophie Brès, Eirini Tagkoudi, Caroline Gaëlle Amiot

We experimentally demonstrate the generation of a short-wave infrared supercontinuum in an uncladded silicon nitride (Si3N4) waveguide with extreme polarization sensitivity at the pumping wavelength of 2.1 µm. The air-clad waveguide is specifically designe ...

Confined dipole and exchange spin waves in a bulk chiral magnet with Dzyaloshinskii-Moriya interaction

Dirk Grundler, Ping Che, Andrea Mucchietto, Helmuth Berger, Jianing Li

The Dzyaloshinskii-Moriya interaction (DMI) has an impact on excited spin waves in the chiral magnet Cu2OSeO3 by means of introducing asymmetry in their dispersion relations. The confined eigenmodes of a chiral magnet are hence no longer the conventional s ...

A Current Propagation Type Return Stroke Model Consistent with the Leader Charge Distribution

Marcos Rubinstein, Farhad Rachidi-Haeri

We describe a current propagation type return stroke model which is consistent with the estimated distribution of the charge on the leader channel. The model takes into account the dispersion of the return stroke current along the return stroke channel. Th ...

Second harmonic generation in glass-based metasurfaces using tailored surface lattice resonances

Olivier Martin, Fabien Sorin, Jérémy Butet, Wei Yan, Dang Tùng Nguyen, Kuang-Yu Yang, Andreas Leber, Chaoqun Dong

Dielectric metasurfaces have shown prominent applications in nonlinear optics due to strong field enhancement and low dissipation losses at the nanoscale. Chalcogenide glasses are one of the promising materials for the observation of nonlinear effects than ...

Distributed optomechanical fiber sensing based on serrodyne analysis

Luc Thévenaz, Zhisheng Yang, Simon Adrien Zaslawski

Distributed measurement of forward stimulated Brillouin scattering (FSBS) attracted substantial attention for its ability to probe media surrounding optical fibers. Currently, all techniques extract the information from the FSBS-induced local energy transf ...

Multi-gas spectroscopy using tailored mid-IR dispersive wave generated in Si3N4 waveguide

Camille Sophie Brès, Davide Grassani, Eirini Tagkoudi

We demonstrate simultaneous detection of acetylene, methane and ethane using milliwatt-level dispersive-wave generated in a Si3N4 waveguide covering 2900 cm-1-3380 cm-1 spectral region. This simple mid-IR absorption spectroscopy scheme achieves hundreds of ...

Phase calibration of a basic bright-field microscope for 3D metrology of transparent samples at the nanoscale

Martinus Gijs, Daniel Migliozzi, Bingying Zhao

Optical retrieval of the structure of transparent objects at the nano-scale requires adapted methods capable of probing their interaction with suitable light. Scattering events, for instance, depend on the content and the arrangement of the medium encounte ...
