Highly Efficient Slow and Fast Light Generation via Brillouin Scattering in As2Se3 Chalcogenide Fiber

Luc Thévenaz, Kwang-Yong Song

Delaying and advancement of optical pulses using stimulated Brillouin scattering in As2Se3 fiber is demonstrated. Pulses can be delayed by 37 ns in a 5-m-long fiber with a pump power as low as 60 mW. ...

Advanced trends in nonlinear optics applied to distributed optical-fibre sensors

Dario Alasia

The distributed optical-fibre sensors based on the properties of Brillouin scattering is the central object of this thesis. In the past decade, optical fibres have gained a large interest as sensors: attractive solutions based on the non-linear stimulated ...

Extreme temperature sensing using Brillouin scattering in optical fibers

Alexandre Fellay

Stimulated Brillouin scattering in silica-based optical fibers may be considered from two different and complementary standpoints. For a physicist, this interaction of light and pressure wave in a material, or equivalently in quantum theory terms between p ...

Observation of the coupling between TA and TO modes in SrTiO3 by Brillouin scattering

Alexander Tagantsev

Brillouin scattering showing an unusual low temperature softening of some transverse modes in SrTiO3 had been reported previously. The earlier data, complemented by newer Brillouin results, and supplemented by high quality hyper Raman data on the soft mode ...

Brillouin-scattering observation of the TA-TO coupling in SrTiO3

Alexander Tagantsev

Brillouin scattering from transverse-acoustic modes of SrTiO3 is observed, while the frequencies of the soft polar modes are remeasured with hyper-Raman scattering. It is shown that an anomalous decrease of sound velocities at low temperatures results from ...

Method for measuring the Brillouin scattering in an optical fibre and device for implementing this method

Luc Thévenaz

This device for measuring Brillouin scattering includes a single laser source (11), a modulator (12) placed on the path of the light emitted by the source (11) and designed to generate a pumping signal and a test signal which are injected to one end (13) o ...

Nitric oxide D2S+ fluorescence quenching by rare gas atoms and van der Waals well depths

Majed Chergui

Studies of the energy and time-resolved fluorescence of NO D2S+ (v = 0) perturbed by inert gas partners (He, Ne, Ar, Kr and Xe) at various pressures were performed by means of synchrotron radiation. With all rare gases, the collision-induced D (v = 0) -> C ...
