The quantum future of microscopy: Wave function engineering of electrons, ions, and nuclei

Thomas La Grange, Fabrizio Carbone, Ivan Madan, Giovanni Maria Vanacore, Simone Gargiulo

The ability to manipulate particles has always been a fundamental aspect for developing and improving scattering and microscopytechniques used for material investigations. So far, microscopy applications have mostly relied on a classical treatment of the e ...

Holographic imaging of electromagnetic fields via electron-light quantum interference

Fabrizio Carbone, Ivan Madan, Enrico Pomarico, Tom Theodorus Antonius Lummen, Gabriele Berruto, Giovanni Maria Vanacore, Tatiana Latychevskaia

Holography relies on the interference between a known reference and a signal of interest to reconstruct both the amplitude and the phase of that signal. With electrons, the extension of holography to the ultrafast time domain remains a challenge, although ...

Spatial coherence properties of an LED-based illumination system for mask-aligner lithography

Hans Peter Herzig, Wilfried Noell, Toralf Scharf, Johana Bernasconi, Raoul Kirner

A high-power LED-based illumination system has been developed as a replacement for the mercury arc lamps used in mask-aligner lithography. LEDs are arranged in a grid array and placed in the entrance aperture of individual reflectors. Those reflectors decr ...

Towards an incoherent off-axis digital holographic microscope

Frédéric Montfort, Christian Depeursinge

We propose and experimentally demonstrate a system in which off-axis digital holographic microscopy is realized using a broadband illumination source. Single-shot holographic measurements are enabled, while the coherence noise is removed thanks to the broa ...

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

Fabrizio Carbone, Luca Piazza, Brett Eugene Barwick, Yoshie Murooka, 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 ...

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 ...

Young's Type Interference for Probing the Mode Symmetry in Photonic Structures

Massimo Gurioli, Laurent Balet

A revisited realization of the Young's double slit experiment is introduced to directly probe the photonic mode symmetry by photoluminescence experiments. We experimentally measure the far field angular emission pattern of quantum dots embedded in photonic ...

Coherence and wavefront characterization of Si-111 monochromators using double-grating interferometry

Christian David

A study of the coherence and wavefront properties of a pseudo-channel-cut monochromator in comparison with a double-crystal monochromator is presented. Using a double-grating interferometer designed for the hard X-ray regime, the complex coherence factor w ...

Extended Focus Optical Coherence Microscopy : Theory and Application

Martin Villiger

Optical coherence tomography (OCT) is an interferometric imaging technique that can provide depth resolved cross-sectional views of biological tissue. OCT employs light with low temporal and yet high spatial coherence. The sample is illuminated point by po ...

Optofluidic pressure sensor based on interferometric imaging

Demetri Psaltis, Wuzhou Song

We present a chip-scale optofluidic interferometric sensor for measuring liquid pressure based on an imaging method. The chip was constructed with a polymer by multilayer soft lithography. It consists of a flexible air gap optical cavity, which, upon illum ...

Controlling Biological Functions

Majed Chergui

A review. Manipulation of the quantum properties of matter can influence the course of biochem. reactions. Can biol. functions, such as vision or photosynthesis, that are driven by incoherent phenomena have anything to do with quantum mechanics, where the ...
