For most design engineers, study of waveguide technology ended when they got their last degree. The only time waveguide comes up is to use it as a last resort in applications such as millimeter-wave ...

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 ...

Researchers have succeeded in making the thinnest ever optical device in the form of a waveguide just three atomic layers thick. The device could lead to the development of higher density ...
