Numerical evidence of exalted nonreciprocal dichroic propagation in a waveguide-coupled magnetoplasmonic chain of ferromagnetic metal stripes

Patterning the metal layer of a ferromagnetic metal-clad III-V waveguide into a chain of coupled magnetoplasmonic nanostripes enhances optical non-reciprocity by two orders. Simulations show how non-reciprocal magnetoplasmonic chain modes couple resonantly to the waveguide.
