In contrast to an analogous waveguide proposed by Yu1 the non-reciprocity at the interface is introduced by the MO properties of the photonic crystal material, namely Bismuth Iron Garnet (BIG, Bi3Fe5O12), a ferrimagnetic oxide which may be easily magnetically saturated by fields of the order of tens of mT. Therefore, this configuration allows to achieve sizable one-way bandwidth by using realistic values of the external magnetic field which makes such a waveguide favorable for design of diode-like elements in optical integrated circuits.
