Unlocking Quantum Possibilities with Subnanometer Optical Fields

Researchers from Zhejiang University have developed a novel waveguiding scheme that can confine light to subnanometer scales, opening up possibilities for advancements in light-matter interactions and super-resolution nanoscopy. This innovative approach allows for the generation of a confined optical field as small as 0.3 nm with an efficiency of up to 95 percent. The breakthrough extends the boundaries of nano-exploration and has potential applications in areas such as atom/molecule manipulation, ultrasensitive detection, and more.
