Electro-Optic Modulator (image) University of Washington Share Print E-Mail Caption The image below envisions an integrated circuit board communicating with light rather than electrons to enable faster and more energy efficient communication. The key is a new electro-optical switch, which rounds up photons on a sub-wavelength scale to translate electrical bit streams to optical bit streams. A customary fiber (size of a human hair) bends in from the left to serve as a reference for size.
