Nanoscale nonreciprocity via photon-spin-polarized stimulated Raman scattering
Abstract
Here, the authors introduce and study theoretically and numerically a scheme for breaking time-reversal symmetry and achieving nonreciprocity on the nanoscale, using spin-selective stimulated Raman scattering. These results could pave the way for compact nonreciprocal communication and computing technologies.
