How do optical fibers work?
To give you the most helpful start, which angle of this amazing technology are you most curious about?
The physics side (how light stays trapped inside the fiber)
Since you are keen on the physics of keeping light trapped, let's start with a foundational concept that makes it all possible: how light changes speed and bends when it moves through different materials. This is governed by a number called the .
