Paper Abstract

Through numerical experiments by finite-element method, we have demonstrated arbitrary-bent-waveguide optical diodes utilizing surface magnon polaritons (SMP) waves on the surface of ferrimagnetic materials. Ferrimagnetic bulk-material slab waveguides and their propagation characteristics of SMP waves are presented. Such surface-wave based waveguides, which could be bent in arbitrary degrees, are shown to be promising elements for one-way transmission as optical diodes. The obtained results show that the optical diodes can have huge isolation coefficient and low insertion loss without requiring nonlinear material and polarization elements. Furthermore, the direction of the optical diode can be controlled by an external magnetic field.
