Modified nonreciprical waveguide formed at the interface between plasmonic metal and uniformly magnetized two-dimensional photonic crystal fabricated from magneto-optic material

Original language description

We have demonstrated numerically that the interface of a metal and uniformly magnetized two-dimensional photonic crystal fabricated from a transparent dielectric magneto-optic (MO) material possesses a one-way frequency range where only a forward propagating surface plasmon polariton (SPP) mode is allowed to propagate. The nonreciprocity at the interface is introduced by the MO properties of the photonic crystal that is fabricated from Bismuth Iron Garnet (BIG, Bi(3)Fe(5)O(12)), 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 significantly smaller values of the external magnetic field than an analogous waveguide proposed by Yu(1) which makes such a waveguide favorable for design of diode-like elements in optical integrated circuits.
