Frequency-comb-assisted broadband precision spectroscopy with cascaded diode lasers

Tobias Kippenberg, Junqiu Liu, Martin Hubert Peter Pfeiffer, Hairun Guo, Arne Kordts, Victor Brasch, Michael Wolfgang Geiselmann

Frequency-comb-assisted diode laser spectroscopy, employing both the accuracy of an optical frequency comb and the broad wavelength tuning range of a tunable diode laser, has been widely used in many applications. In this Letter, we present a novel method ...

Versatile spectral modulation of a broadband source for digital holographic microscopy

Christophe Moser, Tristan Colomb, Gaël Nardin

We demonstrate the potential of spatial light modulators for the spectral control of a broadband source in digital holographic microscopy. Used in a ‘pulse-shaping’ geometry, the spatial light modulator provides a versatile control over the bandwidth and w ...

A monolithic MEMS position sensor for closed-loop high-speed atomic force microscopy

Georg Fantner, Nahid Hosseini, Adrian Pascal Nievergelt, Jonathan David Adams

The accuracy and repeatability of atomic force microscopy (AFM) imaging significantly depend on the accuracy of the piezoactuator. However, nonlinear properties of piezoactuators can distort the image, necessitating sensor-based closed-loop actuators to ac ...

Distributed wireless video caching placement for dynamic adaptive streaming

Pascal Frossard

Caching at edge servers can smooth the temporal traffic variability and reduce the service load of base stations in wireless streaming. However, the assignment of the cached content for possibly multiple versions of different video sequences is still a cha ...

Incremental Consistency Guarantees for Replicated Objects

Rachid Guerraoui, Matej Pavlovic, Dragos-Adrian Seredinschi

Programming with replicated objects is difficult. Developers must face the fundamental trade-off between consistency and performance head on, while struggling with the complexity of distributed storage stacks. We introduce Correctables, a novel abstraction ...

"Can you hear me now?" : Automatic assessment of background noise intrusiveness and speech intelligibility in telecommunications

Raphaël Marc Ullmann

This thesis deals with signal-based methods that predict how listeners perceive speech quality in telecommunications. Such tools, called objective quality measures, are of great interest in the telecommunications industry to evaluate how new or deployed sy ...

Three-dimensional magnetohydrodynamic equilibrium of quiescent H-modes in tokamak systems

Olivier Sauter, Basil Duval, Jonathan Graves, Wilfred Anthony Cooper, Trach-Minh Tran, Jonathan Marc Philippe Faustin, Hamish William Patten, Samuel Lanthaler, Madhusudan Raghunathan, Andreas Kleiner

Three dimensional free boundary magnetohydrodynamic equilibria that recover saturated ideal kink/peeling structures are obtained numerically. Simulations that model the JET tokamak at fixed = 1.7% with a large edge bootstrap current that flattens t ...
