Waveguide Array (IMAGE)
Caption
Microscope image of the laser written waveguide array (left) fabricated in glass by researchers at Penn State to have a geometry that leads to the topological protection of light. Laser light traveling through the ornately microfabricated glass--schematic (right) shows the three-dimensional paths of four waveguides in the device--has been shown to interact with itself to form self-sustaining wave patterns called solitons.
