Optical endoscopy has become an essential diagnostic and therapeutic approach in modern
biomedicine for directly observing organs and tissues deep inside the human body …

We take stock of the progress that has been made into develo** ultrathin endoscopes
assisted by wave front sha**. We focus our review on multicore fiber-based lensless …

For photonic devices, structural disorder and light scattering have long been considered
annoying and detrimental features that were best avoided or minimized. This review shows …

Light transport through a multimode optical waveguide undergoes changes when subjected
to bending deformations. We show that optical waveguides with a perfectly parabolic …

For several centuries, far-field optical microscopy has remained a key instrument in many
scientific disciplines, including physical, chemical, and biomedical research. Nonetheless …

Light propagation in multimode fibers is typically assumed to be extremely sensitive to
changes in geometry. We study here a particular configuration where an S-shaped bend is …

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 …

A modulated sparse random matrix for high-resolution and high-speed 3D compressive
imaging through a multimode fiber A modulated sparse random matrix for high-resolution and …

We performed near-diffraction limited two-photon fluorescence (TPF) imaging through a
lensless, multicore-fiber (MCF) endoscope utilizing digital phase conjugation. The phase …

We investigate the point spread function of a multimode fiber. The distortion of the focal spot
created on the fiber output facet is studied for a variety of the parameters. We develop a …
