Advanced Fiber Optics: Concepts and Technology

Luc Thévenaz

Few technologies have had as much impact on society as fiber optics. These tiny hair-sized glass wires have deeply transformed the way we access information, our modes of communication and even the behavior of consumers. Today, optical fibers are omniprese ...

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 ...

Potentialities of slow and fast light in optical fibers

Luc Thévenaz, Sang Hoon Chin

The ubiquitous role of optical fibers in modern photonic systems has stimulated research to realize slow and fast light devices directly in this close-to-perfect transmission line. Recent progress in developing optically-controlled delays in optical fibers ...

Governing the speed of a light signal in optical fibers

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 ...

Light control and microcavity lasers based on quantum wires integrated in photonic-crystal cavities

Kirill Atlasov

Novel light-emitting devices and micro-optical-circuit elements will rely upon understanding and control of light-matter interaction at the nanoscale. Recent advances in nanofabrication and micro-processing make it possible to develop integrable solid-stat ...

Achievements in slow and fast light in optical fibres

Luc Thévenaz

The ubiquitous role occupied by optical fibres in modern photonic systems has steadily stimulated research to realize slow and fast light devices directly in this close-to-perfect transmission line. This potentially offers the key advantage of a direct and ...

Self-advanced fast light propagation in an optical fiber based on Brillouin scattering

Luc Thévenaz, Sang Hoon Chin

We experimentally demonstrate an extremely simple technique to achieve pulse advancements in optical fibers by using both spontaneous amplified and stimulated Brillouin scattering. It is shown that the group velocity of a light signal is all-optically cont ...

Complete experimental characterization of stimulated Brillouin scattering in photonic crystal fiber

Luc Thévenaz, Stella Foaleng Mafang, Dario Alasia

We provide a complete experimental characterization of stimulated Brillouin scattering in a 160 m long solid-core photonic crystal fiber, including threshold and spectrum measurements as well as positionresolved mapping of the Brillouin frequency shift. In ...

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 ...
