“…One of them, band-tuning via field dependence of the permeability was discussed in a recent review [74]. A quite different magnetic mechanism has been demonstrated by Saado and co-workers [75] in a 3D photonic crystal composed of metal coated disk-shaped magnetic particles floating at a liquid-air interface. They showed that the lattice constant of an ordered array of these magnetic particles can be controlled by an external magnetic field.…”

“…Review articles about the theory and the experimental realizations of MPCs were published by Lyubchanskii et al (2003), Zvezdin and Belotelov (2004), and Inoue (2006). Incorporation of magnetic components into PCs can lead to new and interesting phenomena of magneto-optics such as enhanced MCB and MLB (Inoue and Fujii, 1997;Steel, Levy and Osgood, 2000;Levy, Yang and Steel, 2001;Saado, Golosovsky, Davidov and Frenkel, 2002;Dolgova et al, 2004). The first PC structures were one-dimensional multilayers with dielectric mirrors (λ/4 stacks of materials with high and low refractive index) and a transparent magnetic λ/2 Fabry-Pérot cavity ( Figure 32).…”

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 .

“…This produces strong alterations in cm-and mm-wave transmission spectra. Golosovsky et al [5] reported that disk shaped magnetic particles can self-assembly into various 3D periodic structures; in continuation Saado et al [6] demonstrated that such magnetic PCs possess PB gaps that can be tuned in the microwave regime by means of an applied magnetic field.…”

Two-dimensional photonic crystal infiltrated by liquid crystal: response to applied electric field

We have calculated the photonic band structure of a 2D photonic crystal whose empty cylinders are infiltrated by a liquid crystal; a D.C. electric field is applied in the direction parallel to the cylinders. The local dielectric constant within the cylinders is obtained by minimizing the free energy, which has elastic and electrostatic contributions. We have assumed strong anchoring of the molecules of the nematic liquid crystal at the cylinder boundaries and have averaged over the cross-sectional area of the cylinder. The resulting dielectric tensor is diagonal and depends on the applied field. Moreover, it has the same symmetry as a uniaxial material, so that the optical response of the H-modes and E-modes is given by different dielectric constants ("ordinary" and "extraordinary"). The photonic band structures exhibit a notable dependence on the applied field with shifts up to 6% of the bands. For the E-modes, with a careful choice of the filling fraction it is possible to design a complete photonic gap for a certain range of electric fields, and close the gap for other values of the field. Such behaviour could be applied to optical tuning, switching, and polarizing of light.
