“…Kerr effect, Faraday rotation and optical nonlinearity can be enhanced in MPC due to light localization within magnetic multilayer. Magneto-optical system with large Faraday or Kerr rotation can be used for effective optical isolators [14,15], spatial light-phase modulators [16] and magnetic field and current sensor [17] development. Furthermore, one can obtain stronger enhancement of the magneto-optical phenomena due to resonant effects in the MPCs [18], which characterized by specific polarization properties.…”

This chapter discusses the propagation of TM and TE waves in the one-dimensional gyrotropic magnetophotonic crystals with ferrite and plasma-like layers. Elements of the transfer matrix are calculated in closed analytical form on the base of electrodynamic problem rigorous solution for arbitrary location of the gyrotropic elements on the structure period. Dispersion equation of the layered periodic structure with gyrotropic elements is obtained. Dispersion properties of the structure for TE and TM modes are analyzed for different configurations of magnetophotonic crystals (ferrite and plasmalike layers). Existence areas of transmission bands for surface and bulk waves are obtained. The effect of problem parameters on the dispersion properties of magnetophotonic crystals for TM and TE modes is investigated. Regimes of complete transmission of wave through limited magnetophotonic crystal are analyzed for bulk and surface waves.

“…Nowadays, MOIs based on magnetophotonic crystals (MPCs) are one of the best candidates for integrated isolators [1][2][3][4]. MPCs are a type of photonic crystal (PC) constructed from magnetic materials and are capable of providing unique optical and MO characteristics by exploiting properties of bandgaps and defects [5][6][7][8][9][10][11][12][13][14].…”

Influence of thickness error on the operation of adjustable magneto-optical isolators

We have performed a theoretical study on the case of transmission-type one-dimensional magnetophotonic crystals (MPCs) to establish a practical magneto-optical isolator (MOI) that operates properly even in the presence of construction errors. We have introduced a very thin MPC structure with high transmittance and a large Faraday rotation, with the capability of adjusting to a perfect MOI. A minor thickness error for the individual layers of this MOI may take it from being a perfect MOI; however, its adjustability can provide a stable operation against fabrication errors.

“…Inoue et al [17] reported that one-dimensional magneto-photonic crystals composed of dielectric and magnetic materials exhibit remarkable magneto-optical properties accompanied by a huge enhancement in their Kerr and Faraday rotations,and giant enhancement of nonlinear magneto-optical response [18] was observed. The magneto-optical effect is crucial, which determines the read-write speed of the magnetic recording materials [19] and sensitivity of the magnetic switch [20]. A series of natural photonic crystals based on natural butterfly was reported [9,21], where it was shown that natural butterfly wings have unique features that modulate visible light.…”
