Abstract
Official abstract text for this publication.
A non-reciprocal coupler isolator is provided including a first waveguide. The first waveguide includes a magnetic cladding cover layer magnetized transversely to a propagation direction of the first waveguide. A second waveguide is positioned adjacent to the first waveguide and separated by a gap. The second waveguide includes a non-magnetic cladding cover layer with a refractive index that matches a refractive index of the magnetic cladding cover layer of the first waveguide.
