Integrated Hybrid Plasmonic-Photonic Device for All-Optical Switching and Reading of Spintronic Memory

Abstract

This paper provides a key solution for integrating spintronic memories with photonic integrated circuits, for all-optical switching and reading of nanoscale magnetic bits. Problems associated with nonlinear absorption and the intrinsically weak magneto-optical effect are solved by a hybrid scheme, exploiting plasmonic and photonic resonators. Thus the authors have developed a device concept that paves the way toward ultrafast, energy-efficient advanced on-chip applications.
