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

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 ...

Surface origin and control of resonance Raman scattering and surface band gap in indium nitride

Esther Alarcon Llado

Resonance Raman scattering measurements were performed on indium nitride thin films under conditions where the surface electron concentration was controlled by an electrolyte gate. As the surface condition is tuned from electron depletion to accumulation, ...

Momentum-Resolved Spin Dynamics of Bulk and Surface Excited States in the Topological Insulator Bi2Se3

Helmuth Berger, Philippe Bugnon, Marco Grioni, Alberto Crepaldi

The prospect of optically inducing and controlling a spin-polarized current in spintronic devices has generated wide interest in the out-of-equilibrium electronic and spin structure of topological insulators. In this Letter we show that only measuring the ...

Effect of inhomogeneities on backward and forward Brillouin scattering in Photonic Crystal Fibers

Luc Thévenaz

Photonic Crystal Fibers (PCF) play a crucial role for fundamental investigations such as acousto-optical interactions as well as for applications, such as distributed sensors. One limiting factor for these experiments is the fiber inhomogeneity owing to th ...

Photonic crystal fiber mapping using Brillouin echoes distributed sensing

Luc Thévenaz, Stella Foaleng Mafang

In this paper we investigate the effect of microstructure irregularities and applied strain on backward Brillouin scattering by comparing two photonic crystal fibers drawn with different parameters in order to minimize diameter and microstructure fluctuati ...

Governing the speed of a light signal in optical fibers : Brillouin slow and fast light

Sang Hoon Chin

Dynamic control of the speed of a light signal, based on stimulated Brillouin scattering in optical fibers, was theoretically studied and also experimentally demonstrated as the core object of this thesis. To date, slow light based on stimulated Brillouin ...
