Temporally resolved second-order photon correlations of exciton-polariton Bose-Einstein condensate formation

Benoît Marie Joseph Deveaud, Marcia Portella Oberli, Mitchell David Anderson, Hadis Abbaspour, Albert Adiyatullin

Second-order time correlation measurements with a temporal resolution better than 3 ps were performed on a CdTe microcavity where spontaneous Bose-Einstein condensation is observed. After the laser pulse, the nonresonantly excited thermal polariton populat ...

Surface-Enhanced Hyper-Raman Scattering: A New Road to the Observation of Low Energy Molecular Vibrations

Olivier Martin, Jérémy Butet

The plasmon enhancement of molecular hyper-Raman scattering, the nonlinear counterpart of Raman scattering, which involves the absorption of two fundamental photons, is investigated with emphasis on low energy molecular vibrations. The two-photon excitatio ...

Differential Pulse-Width Pair Brillouin Optical Time-Domain Analysis Employing Raman Amplification and Optical Pulse Coding

Marcelo Alfonso Soto Hernandez

We report on an advanced optical fiber sensing implementation enabling submeter resolution over long distance exploiting Brillouin optical time-domain analysis with differential pulse-width pair. Long sensing distances have been attained thanks to the comb ...

Tunable Enhancement of Raman Scattering in Graphene-Nanoparticle Hybrids

Klaus Kern, Kannan Balasubramanian

The realization of graphene-gold-nanoparticle (G-AuNP) hybrids is presented here through a versatile electrochemical approach, which allows the continuous tuning of the size and density of the particles obtainable on the graphene surface. Raman scattering ...

Widely Tunable Picosecond-Pulsed Source near 2 μm based on Cascaded Raman Wavelength Shifting

Camille Sophie Brès, Adrien Billat, Steevy Joyce Cordette, Yu-Pei Tseng

We demonstrate a cavity-less picosecond pulsed source near 2μm, tunable over more than 200nm based on third order cascaded Raman wavelength shifting. Up to 44% conversion is achieved for 100mW peak powers at 200MHz repetition rate. ...

Extending the Real Remoteness of Long-Range Brillouin Optical Time-Domain Fiber Analyzers

Luc Thévenaz, Sang Hoon Chin, Marcelo Alfonso Soto Hernandez

The real remoteness of a distributed optical fiber sensor based on Brillouin optical time-domain analysis is considerably extended in this paper using seeded second-order Raman amplification and optical pulse coding. The presented analysis and the experime ...

Fano resonances in the nonlinear optical response of coupled plasmonic nanostructures

Olivier Martin, Jérémy Butet

The coupling between metallic nanostructures is a common and easy way to control the optical properties of plasmonic systems. Even though the coupling between plasmonic oscillators has been widely studied in the linear regime, its influence on the nonlinea ...

Optical Fibre optimized for the Reduction of Nonlinear effects

Luc Thévenaz

An optical fibre designed to simultaneously attenuate the effect of modulation instability and stimulated Raman scattering. A first solution proposes to use non-zero dispersion shifted fibres in the normal dispersion regime to reduce both influences at the ...

Brillouin optical time-domain analysis over a 240 km-long fiber loop with no repeater

Luc Thévenaz, Sang Hoon Chin, Marcelo Alfonso Soto Hernandez

In this paper we combine the use of optical pulse coding and seeded second-order Raman amplification to extend the sensing distance of Brillouin optical time-domain analysis (BOTDA) sensors. Using 255-bit Simplex coding, the power levels of the Raman pumps ...
