Effect of fiber orientation on the in-plane tensile response of UHPFRC reinforcement layers

Eugen Brühwiler, Emmanuel Denarié, Maléna Bastien Masse

The application on existing Reinforced Concrete (RC) slabs of cast-on site Ultra-High Performance Fiber Reinforced cement-based Composite UHPFRC) layers is a very efficient reinforcement technique, currently spreading. For the design of these tensile reinf ...

Confocal microscopy through a multimode fiber using optical correlation

Demetri Psaltis, Christophe Moser, Damien Claude-Marie Loterie

We report on a method to obtain confocal imaging through multimode fibers using optical correlation. First, we measure the fiber's transmission matrix in a calibration step. This allows us to create focused spots at one end of the fiber by shaping the wave ...

Delivery of focused short pulses through a multimode fiber

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

Light propagation through multimode fibers suffers from spatial distortions that lead to a scrambled intensity profile. In previous work, the correction of such distortions using various wavefront control methods has been demonstrated in the continuous wav ...

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 ...

Kerr nonlinearity of Thulium-doped fiber near 2 um

Camille Sophie Brès, Svyatoslav Kharitonov, Adrien Billat, Steevy Joyce Cordette, Ludovic Zulliger

The nonlinear coefficient and group velocity dispersion of a thulium-doped fiber near 2μm are evaluated via four-wave mixing. Nonlinearity of thulium-doped fiber can be used for the design of doped-fiber lasers in this spectral region. ...

Isolator-free unidirectional thulium-doped fiber laser

Camille Sophie Brès, Svyatoslav Kharitonov

We report the first demonstration of a unidirectional, isolator-free 2-mmthulium-doped fiber (TDF) laser, relying on the properties of the theta cavity (ring resonator with S-shaped feedback). The core pumped theta cavity TDF laser provides sub-Watt output ...

Digital confocal microscopy through a multimode fiber

Demetri Psaltis, Christophe Moser, Ioannis Papadopoulos, Damien Claude-Marie Loterie, Salma Farahi, Alexandre Goy

Confocal laser-scanning microscopy is a well-known optical imaging method where a pinhole is used in the illumination and detection pathways of a normal microscope, in order to selectively excite and detect a particular focal volume. The advantage of this ...

Delivery of ultrashort spatially focused pulses through a multimode fiber

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

Multimode optical fibers potentially allow the transmission of larger amounts of information than their single mode counterparts because of their high number of supported modes. However, propagation of a light pulse through a multimode fiber suffers from s ...

Light control in a multicore fiber using the memory effect

Demetri Psaltis, Christophe Moser, Nicolino Stasio, Donald Benjaman Conkey

Endoscopic imaging through a multicore fiber (MCF) is widely used but is affected by pixelated images, which limits its resolution to a few micrometers. This is due to the spacing between the cores in the MCF, which is large enough to avoid core-to-core li ...
