Integrated nanophotonics: dynamic optical isolation, and nanoscale far-field focusing in aperiodic plasmonic waveguide array

摘要

We show that dynamic modulation of nanophotonic structures achieves complete optical isolation and non-reciprocal optical circulator using standard non-magnetic optoelectronic materials. We also numerically demonstrate nano-scale far-field focusing in an aperiodic array of plasmonic waveguides.
