Signal control with light frequencies

In a review article in Nature Photonics Ferenc Krausz and Mark Stockman discuss the prospects, recent experimental and theoretical findings open for the future of signal processing

Light waves have the potential to boost the efficiency of conventional electronics by a factor of 100,000. In a review article that appears in “Nature Photonics” on March 14th, Prof. Ferenc Krausz of the Laboratory for Attosecond Physics (LAP) at the Max-Planck-Institut für Quantenoptik and the Ludwig-Maximilians-Universität München and his co-author Prof. Mark Stockman of Georgia State University (GSU) in Atlanta describe how this vision may one day come true. In their scenario, one would exploit the electric field of laser light to control the flow of electrons in dielectric materials, which, in turn, may modulate transmitted light and switch current in electronic circuits at light frequencies.
