Researchers have built a microscopic 3D-printed optical device that funnels light from 37 separate multimode semiconductor lasers into a single optical fiber, merging 222 distinct spatial modes; the ...

A Ball Lens consists of a highly transparent spherical ball, usually made of solid glass (fused silica) or another optical material with index of refraction less than 2. Most ball lenses are made with ...

Microendoscopes using fiber optics are becoming increasingly important imaging tools, but they have physical limitations. They are essential for applications that require a long working distance, high ...
