Feasibility of usage of surface plasmons in a new design of an integrated optical
isolator has been studied. In the case of surface plasmons propagating at a
boundary between a transition metal and a double-layer dielectric, there is a
significant difference of optical loss for surface plasmons propagating in
opposite directions. Utilizing this structure, it is feasible to fabricate a
competitive plasmonic isolator, which benefits from a broad wavelength
operational bandwidth and a good technological compatibility for integration into
the Photonic Integrated Circuits (PIC). The linear dispersion relation was
derived for plasmons propagating in a multilayer magneto-optical slab.
