What's Happening?
Researchers have developed a tunable Metafiber that allows for precise control of light focus using a 3D nanoprinted hologram on the end face of a dual-core fiber. This innovation, led by Professor Markus A. Schmidt, enables remote focus control by adjusting the relative power between the fiber's guided modes. The hologram is sensitive to changes in the interference pattern of light emitted from each core, allowing for a shift in the focal spot's position without moving parts. This approach offers compact, robust, and fast tunable focusing, advancing the field of reconfigurable photonics.
