Delivery of ultrashort spatially focused pulses through a multimode fiber for two photon endoscopic imaging

Demetri Psaltis, Christophe Moser, Salma Farahi, Edgar Emilio Morales Delgado

Due to their high number of supported modes, multimode optical fibers carry large amount of spatio-temporal information. However, propagation of a light pulse through a multimode optical fiber suffers from spatial distortions due to superposition of the va ...

Remote macroscopic entanglement on a photonic crystal architecture

Vincenzo Savona, Momchil Minkov, Hugo Pierre Alexandre Flayac

The outstanding progress in nanostructure fabrication and cooling technologies allows what was unthinkable a few decades ago: bringing single-mode mechanical vibrations to the quantum regime. The coupling between photon and phonon excitations is a natural ...

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

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

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 ...

Light trapping polymer-based coatings for cost effective flexible thin film photovoltaics

Marina Aymara González Lazo

Thin film silicon solar cells benefit from a lower fabrication cost than crystalline silicon cells, but they have a lower efficiency. The aim of this thesis was to explore the light-management capabilities of sub-micron polymer-based textures, both for the ...

Sub-femtosecond precision measurement of relative X-ray arrival time for free-electron lasers

Christoph Peter Hauri, Christoph Bostedt

Today's brightest coherent X-ray sources, X-ray free-electron lasers, produce ultrafast X-ray pulses for which full-width at half-maximum durations as short as 3 fs have been measured(1). There has been a marked increase in the popularity of such short pul ...

On Micro Optical Elements for Efficient Light Diffusion

Roland Andreas Bitterli

Efficient light management is one of the key issues in modern energy conversion systems, be it to collect optical power or to redistribute light generated by high power light emitters. This thesis touches mainly on the subject of efficient light redistribu ...

Functional and Structural Imaging with Optical Coherence Microscopy : Principles & Applications

Arno Pino Bouwens

Fluorescence microscopy techniques are well established research tools and have proven their use in a large variety of biomedical applications. Microscopic molecular contrast is achieved by imaging fluorescent dyes that bind specifically to a molecule of i ...

Full field vertical scanning in short coherence digital holographic microscope

Frédéric Montfort, Etienne Cuche, Christian Depeursinge, Christophe Moser

In Digital holography Microscopes (DHM) implemented in the so-called "off axis" configuration, the object and reference wave fronts are not co-planar but form an angle of a few degrees. This results into two main drawbacks. First, the contrast of the inter ...

Resonant PZT MEMS Scanner for High-Resolution Displays

Paul Muralt, Sven Holmström, Davide Balma

A resonant piezoelectric scanner is developed for high-resolution laser-scanning displays. A novel actuation scheme combines the principle of mechanical amplification with lead zirconate titanate (PZT) thin-film actuation. Sinusoidal actuation with 24 V at ...
