The future powered by Polariton
The plasmonics modulator technology has been developed for more than 6 years at ETH Zurich, Switzerland. Key to our technology is the coupling of light with electrons at a metal surface. Light is coupled to the metal surface as Surface Plasmon Polaritons (SPPs). This way we are able to confine light below the diffraction limit.
