Soliton Instabilities and Vortex Street Formation in a Polariton Quantum Fluid

Benoît Marie Joseph Deveaud, Gaël Nardin, Gabriele Grosso, François Morier-Genoud

Exciton polaritons have been shown to be an optimal system in order to investigate the properties of bosonic quantum fluids. We report here on the observation of dark solitons in the wake of engineered circular obstacles and their decay into streets of qua ...

Lateral shearing interferometry of high-harmonic wavefronts

Christopher Alexander Arrell

We present a technique for frequency-resolved wavefront characterization of high harmonics based on lateral shearing interferometry. Tilted replicas of the driving laser pulse are produced by a Mach-Zehnder interferometer, producing separate focii in the t ...

Ultrabroadband TW-class Ti:sapphire laser system with adjustable central wavelength, bandwidth and multi-color operation

Christoph Peter Hauri

We demonstrate a versatile tunable and highly stable ultrabroadband Ti:sapphire chirped pulse amplification system with a compressed pulse energy of 20 mJ at 100 Hz repetition rate. High power Ti: Sa systems in principle do not offer wavelength tunability ...

10Gbps Parametric Short-Wave Infrared Transmitter

Camille Sophie Brès

We demonstrate the first 10Gb/s parametric transmitter in short-wave Infrared band. The device operates by converting 1278nm signal over 85THz to generate channel at 2002nm using highly-nonlinear-fiber and was characterized by error-free performance. ...

Extension of Unified Formulation for the FDTD Simulation of Nonlinear Dispersive Media

Ali Naqavi, Sina Khorasani

A simple approach is extended for the simulation of Kerr-nonlinear and/or dispersive media through the finite-difference time-domain method. The scheme is able to include different types of linear and nonlinear dispersion in a single and unified formulatio ...

Optofluidic applications with lithium niobate nanowires

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh, Jae-Woo Choi

We report the hydrothermal synthesis of free-standing lithium niobate nanowires. We show that the versatile properties of bulk lithium niobate such as nonlinear optical effects can be exploited at the nanoscale. We describe the fabrication of polydimethyls ...

OPTIMIZATION OF THE POSITION OF THE RADIAL LOOP PICKUPS IN THE CERN PS

Sandra Aumon

A part of the beam losses at transition crossing of high intensity beams in the CERN PS have been attributed to an excursion of the closed orbit. The orbit jump occurs simultaneously with the jump of the transition energy triggered by pulsed quadrupoles. I ...

Inline holographic coherent anti-Stokes Raman microscopy

Demetri Psaltis, Ho Ling Li, Kun Shi

We demonstrate a simple approach for inline holographic coherent anti-Stokes Raman scattering (CARS) microscopy, in which a layer of uniform nonlinear medium is placed in front of a specimen to be imaged. The reference wave created by four-wave mixing in t ...

Polarization modes in long-wavelength Vertical-Cavity Surface-Emitting Lasers (VCSELs) and VCSEL-arrays

Elyahou Kapon, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Elodie Lamothe, Lukas Mutter

Spatial transverse modes and polarization states are experimentally studied in single vertical cavity surface emitting lasers (VCSELs) and phased-locked VCSEL arrays emitting at 1.3 mu m wavelength. Analysis of the polarization-resolved near fields, far fi ...

The stress-assisted enhancement of piezoelectric properties due to mechanically incompatible domain structures in BaTiO3

Nava Setter, Alexander Tagantsev, Dragan Damjanovic, Tomas Sluka, Enrico Colla, Mahamudu Mtebwa

The piezoelectric properties of tetragonal BaTiO3 (BTO) crystals with a high density of 90° twin domain boundaries were experimentally investigated by Wada and Tsurumi (2004 Br. Ceram. Trans. 103 93). These crystals with engineered dense domain structures ...
