Minimally invasive endoscopes are indispensable in biomedicine. Coherent fiber bundles
(CFBs) enable ultrathin lensless endoscopes. However, the propagation of light through a …

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 …

When multimode optical fibers are perturbed, the data that is transmitted through them is
scrambled. This presents a major difficulty for many possible applications, such as …

High-fidelity image transmission through multimode fiber is critical for the biomedical
imaging and telecommunications industries. However, mode coupling and modal dispersion …

An improved deep neural network incorporating attention mechanism and DSSIM loss
function (AM_U_Net) is used to recover input images with speckles transmitted through a …

Multimode fiber endoscopes provide extreme miniaturization of imaging components for
minimally invasive deep tissue imaging. Typically, such fiber systems suffer from low spatial …

A multimode fiber represents the ultimate limit in miniaturization of imaging endoscopes.
However, such a miniaturization usually comes as a cost of a low spatial resolution and a …

In recent years, the technology of multi-mode fiber (MMF) output speckle recognition has
