“…This aim could be reached in a very good approximation by Kato et al (2003) with a bilayer number k = 6, an enhancement of θ F by a factor of 150, and an absorption in the order 10 −6 . Figure 33 (inset) gives an impression of the high finesse of the spectral enhancement of both the optical transmission and the Faraday rotation (enhancement factor 50) of a related MPC, (SiO 2 /Ta 2 O 3 ) 5 /Bi:YIG/(SiO 2 /Ta 2 O 3 ) 5 (Murzina et al, 2004).…”

“…As a result of this combination, SHG and third-harmonic generation (THG) become very sensitive to control by external magnetic impacts. MSHG has, for example, been observed in MPC microcavities formed from a half-wavelength-thick Bi:YIG film sandwiched between two high-finesse dielectric Bragg reflectors (Murzina et al, 2004;Fedyanina et al, 2004). Apart from the well-known enhancement of the Faraday rotation (Figure 33, inset), this 1D MPC reveals SHG for both s-and p-polarized fundamental radiation, which is resonance enhanced at least by a factor of 10 3 as compared to the intensity outside the PBG (Figure 33, main panel).…”

After introducing the concepts of linear and nonlinear magneto‐optics in the visible spectral range, the flourishing field of X‐ray circular and linear dichroism is briefly discussed with pertinent examples. The experimental part starts with the basic idea of magneto‐optic ellipsometry and then focuses on the development of new experimental techniques like vector magneto‐optical Kerr effect (MOKE), diffracted MOKE, dynamic MOKE, nonlinear MOKE, and magneto‐optic X‐ray microscopy. Specified and timely material aspects are finally discussed under the topics magneto‐optical storage materials, magnetic semiconductors, antiferromagnets, and magnetophotonic crystals. It is stressed that the magneto‐optical probe is indispensable in the limits of very short times ( femtomagnetism ), that it plays a leading role in the development of spintronics , and that nano‐ and microstructured magnetic materials have opened the new field of magnetophotonics .

“…In this manner, many modern optical instruments have been realized employing photonic-crystal-based cavities [43], waveguides [44], collimators [45], or beam-splitters [46] with unique properties inaccessible in classical media, e.g., the high quality factor of resonators and low attenuation in waveguides based on lossless frequency-selective mirrors or claddings, respectively. It is also desirable to appreciate the capability of the formalism to deal with generally anisotropic media, e.g., magnetically ordered materials forming magneto-photonic crystals, because they offer further opportunities such as highly efficient optical isolation [47], unidirectional and time-reversal asymmetry [48], nonreciprocity causing a broad range of mode group velocities down to frozen modes [49,50] (usable for signal delay lines or optical buffers for data storage), or magneto-optically induced second-and third-harmonic generation [51,52].…”

The analytical formalism of Rokushima and Yamakita [J. Opt. Soc. Am. 73, 901-908 (1983)] treating the Fraunhofer diffraction in planar multilayered anisotropic gratings proved to be a useful introduction to new fundamental and practical situations encountered in laterally structured periodic (both isotropic and anisotropic) multilayer media. These are employed in the spectroscopic ellipsometry for modeling surface roughness and in-depth profiles, as well as in the design of various frequency-selective elements including photonic crystals. The subject forms the basis for the solution of inverse problems in scatterometry of periodic nanostructures including magnetic and magneto-optic recording media. It has no principal limitations as for the frequencies and period to radiation wavelength ratios and may include matter wave diffraction. The aim of the paper is to make this formalism easily accessible to a broader community of students and non-specialists. Many aspects of traditional electromagnetic optics are covered as special cases from a modern and more general point of view, e.g., plane wave propagation in isotropic media, reflection and refraction at interfaces, Fabry-Perot resonator, optics of thin films and multilayers, slab dielectric waveguides, crystal optics, acousto-, electro-, and magneto-optics, diffraction gratings, etc. The formalism is illustrated on a model simulating the diffraction on a ferromagnetic wire grating.

“…One-way edge modes analogous to quantum Hall edge states in twodimensional photonic crystals in gyrotropic media were investigated by Haldane, Raghu and other authors [9][10][11]. Magnetization-induced second-harmonic-generation in magneto-photonic crystals was studied by Murzina and co-workers [12]. Levy and coworkers reported on flat-top response in multiple resonator one-dimensional magnetophotonic crystals [13] and large polarization rotations in waveguide nonreciprocal Bragg systems [14][15][16].…”

Elliptical normal modes and stop band reconfiguration in multimode birefringent one-dimensional magnetophotonic crystals

et al. 2011

This study examines photonic stop band reconfiguration upon magnetization reversal in multimode elliptically birefringent Bragg filter waveguides. Magnetization reversal in longitudinally-magnetized magneto-optic waveguides affects the character of the local orthogonal elliptically-polarized normal modes, impacting the filter's stop band configuration.Unlike the standard case of circular birefringence in magneto-optic media, opposite helicity states do not transform into each other upon magnetization reversal for a given propagation direction. Rather, helicity reversals yield new and different normal modes, with perpendicularlyoriented semi-major axes, corresponding to a north-south mirror reflection through the equatorial plane of the Poincaré sphere. For asymmetric contra-directional coupling between different-order waveguide modes in multimode magneto-photonic crystals, this symmetry breaking, namely, the obliteration of normal modes upon magnetization reversal, allows for strongly reconfigured stop bands, through the hybridization of the elliptically-polarized states. The effect of Bloch mode reconfiguration on the stop band spectral profile contributes to the magnetic response of the filter. In such elliptically birefringent media, input polarization helicity reversal also becomes a 2 powerful tool for optical transmittance control. Both magnetization and helicity reversals can thus serve as useful tools for the fabrication of on-chip magneto-photonic crystal switches.3
