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.
