Light-Matter Interaction in III-Nitride Waveguides: Propagating Polaritons and Optical Gain

Joachim Armand Simonne Ciers

III-nitride waveguides featuring AlInN claddings and GaN/AlGaN quantum wells (QWs) offer promising perspectives for applications in many fields of short-wavelength photonics. Thanks to their nearly lattice-matched nature, these structures exhibit an excell ...

We investigate optical second-harmonic generation (SHG) from metasurfaces where noncentrosymmetric V-shaped gold nanoparticles are ordered into regular array configurations. In contrast to expectations, a substantial enhancement of the SHG signal is observ ...

Resonant waveguide gratings (RWGs), also known as guided mode resonant (GMR) gratings or waveguide-mode resonant gratings, are dielectric structures where these resonant diffractive elements benefit from lateral leaky guided modes from UV to microwave freq ...

We present our recent progress pertaining to the synthesis and analysis of bianisotropic linear and nonlinear metasurfaces. These developments are based on the generalized sheet transition conditions (GSTCs), which provide a very complete and general metho ...

IEEE2018

Silicon nitride waveguides offer excellent linear and nonlinear properties that can be exploited from the visible to the middle infrared. Here we will cover recent efforts on pushing performances of 3rd and 2nd order nonlinear wave mixing in such waveguide ...

We propose for the first time template-assisted dewetting of high-index chalcogenide glasses for low-cost manufacturing of all-dielectric metasurfaces on large-area flexible and stretchable substrates. ...

Bloch surface waves (BSWs) are surface electromagnetic modes that propagate at the interface between a multilayer substrate and a homogeneous external medium. The optical field of the surface mode is confined near the surface of the multilayer. This vertic ...

Revealing a Mode Interplay That Controls Second-Harmonic Radiation in Gold Nanoantennas

Olivier Martin, Jérémy Butet, Gabriel David Bernasconi, Chen Yan

In this work, we investigate the generation of second- harmonic light by gold nanorods and demonstrate that the collected nonlinear intensity depends upon a phase interplay between di ff erent modes available in the nanostructure. By recording the backward ...

Wavevector-Selective Nonlinear Plasmonic Metasurfaces

Olivier Martin, Jérémy Butet, Chen Yan, Kuang-Yu Yang

Electromagnetic metasurfaces with strong non- linear responses and angular selectivity could o ff er many new avenues for designing ultrathin optics components. We investigated the optical second harmonic generation from plasmonic metasurfaces composed of ...

Large second harmonic generation enhancement in Si3N4 waveguides by all-optically induced quasiphase- matching

Tobias Kippenberg, Camille Sophie Brès, Davide Grassani, Martin Hubert Peter Pfeiffer, Svyatoslav Kharitonov, Adrien Billat

Efficient second harmonic generation in integrated platforms is usually achieved by resonant structures, intermodal phase-matching or quasi-phase matching by periodically poling ferroelectric waveguides. However, in all these structures, it is impossible t ...
