Rotating Soliton

Caption

Animation showing a topological soliton rotating anticlockwise. Laser light traveling through waveguides, intricate "wires for light" carved through glass, interacts with itself to form self-sustaining wave patterns called solitons. The spiral rotation of the solitons is a signature of the specific shape of the waveguides and an indicator that the device is topological.
