Researchers have developed a microscopic 3D-printed optical device that can efficiently combine light from dozens of small semiconductor lasers into a single multimode optical fiber with very low loss ...

With their internal memory, recurrent neural networks can be used to learn and predict time-dependent behaviours. In their recent work, Salmela et al. 1 present a recurrent neural network architecture ...

Super-resolution microscopy is typically not applicable to in situ imaging through a narrow channel due to the requirement for complex optics. Although multimode fibres (MMFs) have emerged as a ...

Multimode fiber (MMF) consists of a light-guiding core embedded in a cladding with a diameter of typically only 125 µm, about the thickness of a human hair. Unlike single mode fiber, which has a core ...

A new imaging technique, allowing 3D imaging at video rates through a fiber the width of a human hair, could transform imaging for a wide range of applications in industrial inspection and ...

Optical fibers are fundamental components in modern science and technology due to their inherent advantages, providing an efficient and secure medium for applications such as internet communication ...

Researchers have devised a novel technique to 'flip' the optical wavefront of an image for both polarizations simultaneously, so that it can be transmitted through a multimode fiber without distortion ...

Integration of rugged fiber optics and chiclet-based optical transceivers promotes durability, miniaturization, and modularity for aerospace and defense applications. Difference between rugged fiber ...
