waveguides

How Do Waveguides Work in Nanotechnology?

Nanoscale waveguides exploit the principles of electromagnetic confinement and plasmonics. They can confine light to regions smaller than the wavelength of the light itself, allowing for high precision and miniaturization in devices. This is achieved through materials with specific refractive indices and the use of surface plasmon polaritons (SPPs) which are electromagnetic waves that travel along the surface of a conductor.
