Counting the cycles of light using a self-referenced optical microresonator

Tobias Kippenberg, Tobias Herr, Martin Hubert Peter Pfeiffer, Victor Brasch, John David Jost, Caroline Marie Anne Lecaplain

Phase coherently linking optical-to-radio frequencies with femtosecond mode-locked laser frequency combs has enabled counting the cycles of light and is the basis of optical clocks, absolute frequency synthesis, tests of fundamental physics, and improved s ...

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 ...

Acquisition of multiple phase derivatives from a single frame in digital holographic interferometry

Pramod Rastogi, Rishikesh Dilip Kulkarni

This paper proposes a technique to extract two-dimensional multiple phase derivatives (strains, slopes, and shearing strains) from a single frame of the interference fringe pattern recorded in an optical setup with multiple illumination beams. In the propo ...

Portable advanced off-axis camera for quantitative phase microscopy

Christian Depeursinge

We propose and experimentally demonstrate a device in which common-path interferometry combined with off-axis holographic geometry is used to realize a digital holographic camera which can be attached to the camera port of a conventional transmission micro ...

Off-axis digital holographic camera for quantitative phase microscopy

Frédéric Montfort, Christian Depeursinge, Christophe Moser, Zahra Monemhaghdoust

We propose and experimentally demonstrate a digital holographic camera which can be attached to the camera port of a conventional microscope for obtaining digital holograms in a self-reference configuration, under short coherence illumination and in a sing ...

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 ...

Live-cell multiplane three-dimensional super-resolution optical fluctuation imaging

Marcel Leutenegger, Theo Lasser, Aurélien Godinat, Françoise Gisou van der Goot Grunberg, Patrick Alain Sandoz, Noelia Laura Bocchio, Azat Sharipov, Stefan Geissbuehler

Super-resolution optical fluctuation imaging (SOFI) provides an elegant way of overcoming the diffraction limit in all three spatial dimensions by computing higher-order cumulants of image sequences of blinking fluorophores acquired with a classical widefi ...

Optical Coherence Correlation Spectroscopy

Stéphane Broillet

Questions such as biomolecular interactions, kinetics of enzymes, DNA conformational changes, cellular structures properties (among others) are addressed by characterizing the biological function of molecules. This function depends on their structure and t ...
