Communication: Toward ultrafast, reconfigurable logic in the nanoscale

摘要

We propose and illustrate numerically a class of nanoscale, ultrafast logic gates with the furthernadvantage of reconfigurability. Underlying the operation of the gates and their versatility is the con-ncept of polarization control of the electromagnetic energy propagating via metal nanoparticle arrays.nSpecifically, a set of different logic gates is shown to obtain from a single metal nanoparticle junctionnby modification of the polarization properties of the input light sources. Implications and extensionsnof the gates are discussed. © 2011 American Institute of Physics. [doi:10.1063/1.3626553]
