Wide-band slow light in compact photonic crystal coupled-cavity waveguides

Vincenzo Savona, Momchil Minkov

Slow light has a variety of applications, in particular for enhanced nonlinear effects like four-wave mixing and high-harmonic generation. Here, we propose a photonic crystal coupled-cavity waveguide with an ultracompact arrangement of the constituent cavi ...

Simultaneous observation of the quantization and the interference pattern of a plasmonic near-field

Fabrizio Carbone, Brett Eugene Barwick, Yoshie Murooka, Luca Piazza, Tom Theodorus Antonius Lummen

Surface plasmon polaritons can confine electromagnetic fields in subwavelength spaces and are of interest for photonics, optical data storage devices and biosensing applications. In analogy to photons, they exhibit wave-particle duality, whose different as ...

Optical process and optical device, allowing to avoid unwanted nonlinear effects in an optical fiber

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

The invention concerns a process comprising the following steps: injecting, in an optical fiber, N time limited replica optical signals at distinct frequencies, each replica signal being temporally shifted relative to the other replica signals; then propag ...

Study of constrained Brownian motion of nanoparticles near an interface using optical tweezers

Martinus Gijs, Thomas Lehnert, Matteo Cornaglia, Raphaël Etienne Jean Trouillon, Hui Yang

We demonstrate a method to determine the Brownian motion and the diffusion coefficient of a nanoparticle in water in a plane that is parallel to a solid boundary and as function of the distance normal to that boundary by using an optical tweezers instrumen ...

Experimental evaluation of the velocity profiles and performance of a counter rotating micro-turbine by 2D laser Doppler velocimetry

François Avellan, Elena Vagnoni, Loïc Andolfatto, Cécile Münch-Alligné

The most exploited renewable energy at a global scale is hydropower, which nowadays accounts for the 18 % of the world’s electricity supply. Its production is expected to increase approximately 3.1% each year in the next 25 years maintaining its share in t ...

Multilevel Micro-Structuring of Glassy Carbon Molds for Precision Glass Molding

Hans Peter Herzig, Toralf Scharf, Karin Prater

Replication techniques for diffractive optical elements (DOEs) in soft materials such as plastic injection molding are state of the art. For precision glass molding in glasses with high transition temperatures, molds with extreme thermal resistivity, low c ...

Coherent creation and destruction of orbital wavepackets in Si:P with electrical and optical read-out

The ability to control dynamics of quantum states by optical interference, and subsequent electrical read-out, is crucial for solid state quantum technologies. Ramsey interference has been successfully observed for spins in silicon and nitrogen vacancy cen ...

Optical-resolution photoacoustic imaging through thick tissue with a thin capillary as a dual optical-in acoustic-out waveguide

Demetri Psaltis, Christophe Moser, Nicolino Stasio, Emmanuel André Henri Bossy

We demonstrate the ability to guide high-frequency photoacoustic waves through thick tissue with a water-filled silica-capillary (150 mu m inner diameter and 30 mm long). An optical-resolution photoacoustic image of a 30 mu m diameter absorbing nylon threa ...

Nanoskiving Core-Shell Nanowires: A New Fabrication Method for Nano-optics

Anna Fontcuberta i Morral, Martin Heiss, Eleonora Russo, Yannik Fontana

This paper describes the fabrication of functional optical devices by sectioning quantum-dot-in-nanowires systems with predefined lengths and orientations. This fabrication process requires only two steps, embedding the nanowires in epoxy and using an ultr ...

Polarization-multiplexed encoding at nanometer scales

Carlos Alberto Macias Romero

Optical data storage was developed using binary encoding primarily due to signal to noise ratio considerations. We report on a multiplexing method that allows a seven fold storage increase, per storage layer, per side, and propose one that can yield theore ...
