Brainy UK scientists create robust optic fiber that may unlock our quantum future
A regular optical fiber consists of three elements: the core, the cladding, and the coating. Finally, the coating works as the primary buffer and a jacket encases the entire structure. It’s free, every week, in your inbox. Whenever you fabricate a fiber-optic cable, small variations in the physical structure of the fiber are inevitably present. This is where we found the ideas of topology useful, Roberts added. These so-called edge states are shielded from disorder in the overall structure....
