Three-dimensional microfabrication through a multimode optical fiber

Demetri Psaltis, Christophe Moser, Loïc Urio, Nicolino Stasio, Edgar Emilio Morales Delgado, Donald Benjaman Conkey

3D printing based on additive manufacturing is an advanced manufacturing technique that allows the fabrication of arbitrary macroscopic and microscopic objects. Many 3D printing systems require large optical elements or nozzles in proximity to the built st ...

Control of pulsed light propagation through multimode optical fibers

Edgar Emilio Morales Delgado

Visualization of organs and cells in the interior of living beings is a challenging task due to the light absorption and multiple light scattering occurring in biological tissue that prevents the di-rect transmission of images. A standard visualization app ...

Two-photon excitation endoscopy through a multimode optical fiber

Demetri Psaltis, Christophe Moser, Edgar Emilio Morales Delgado

The vast number of propagating solutions to the wave equation in multimode optical fibers represents a larger information capacity than provided by fiber bundles of the same diameter. Therefore, in the field of imaging, multimode fibers potentially allow t ...

Complex light in 3D printing

Demetri Psaltis, Christophe Moser, Damien Claude-Marie Loterie, Edgar Emilio Morales Delgado, Miguel Antonio Modestino, Paul Delrot

3D printing as a tool to generate complicated shapes from CAD files, on demand, with different materials from plastics to metals, is shortening product development cycles, enabling new design possibilities and can provide a mean to manufacture small volume ...

Bending Compensating Device, System and Method for Optical Waveguides

Demetri Psaltis, Christophe Moser, Damien Claude-Marie Loterie, Edgar Emilio Morales Delgado, Sebastien Walpen

A bending compensation device for a waveguide, including a direction changing device configured to maintain a constant bending angle to the waveguide, a distal end of the waveguide having a first orientation, and the proximal end of the waveguide having a ...

Lensless two-photon imaging through a multicore fiber with coherence-gated digital phase conjugation

Demetri Psaltis, Christophe Moser, Nicolino Stasio, Edgar Emilio Morales Delgado, Donald Benjaman Conkey, Marilisa Romito

We performed near-diffraction limited two-photon fluorescence (TPF) imaging through a lensless, multicore-fiber (MCF) endoscope utilizing digital phase conjugation. The phase conjugation technique is compatible with commercially available MCFs with high co ...

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 ...

Delivery of an ultrashort spatially focused pulse to the other end of a multimode fiber using digital phase conjugation

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 ...

Two-photon imaging through a multimode fiber

Demetri Psaltis, Christophe Moser, Edgar Emilio Morales Delgado

In this work we demonstrate 3D imaging using two-photon excitation through a 20 cm long multimode optical fiber (MMF) of 350 mu m diameter. The imaging principle is similar to single photon fluorescence through a MMF, except that a focused femtosecond puls ...
