Abstract:
A two-dimensional photonic crystal formed of a square lattice of dielectric rods immersed in air, in which are inserted, in a controlled manner, defects that originate three waveguides and one resonant cavity. The cavity is formed of a ferrite cylinder with magneto-optical properties, and by two dielectric cylinders located near to the ferrite cylinder. It has the function of transmitting electromagnetic signals in a desired direction (clockwise or counterclockwise), defined by the sign of an external DC magnetic field H0.
