Work
The rapid transmission of signals over long distances is fundamental to the flow of information in our time. Since the 1930s thin filaments, or fibers, of glass have been used to see inside the body, but these long remained unusable for long-distance information transfer because too much light was lost along the way. In the 1960s Charles Kao presented a solution: fibers of very pure glass transported sufficient light. Together with laser technology, his solution has made telecommunication using optical fibers possible.
