Transport properties of MOPhC/metal one‐way waveguide

We have demonstrated numerically that the interface between metal and uniformly magnetized 2D photonic crystal(PC) fabricated from a transparent dielectric magneto‐optic(MO) material possesses a one‐way frequency range where only a forward propagating surface plasmon polariton mode is allowed to propagate. By using a simple theoretical model we have shown that nonreciprocity is introduced by the MO properties of the PC. Transport properties of the structures within this frequency range have been investigated by FDTD method which enables to calculating propagation of EM waves through media with full tensorial MO permittivity. We found that in the presence of a time‐dependent external magnetic field interesting features associated with the redistribution of the EM field appear.
