When the constitutive materials of photonic crystals (PCs) are magnetic, or even only a defect in PCs is magnetic, the resultant PCs exhibit very unique optical and magneto-optical (MO) properties. They are called magnetophotonic crystals (MPCs) providing the spin-dependent nature in PCs. The strong photon confinement in the vicinity of magnetic defects(More)
We study the optical properties of a photonic crystal interfaced with a uniform medium with the negative dielectric constant or with another photonic crystal. We show that, at such an interface, nonpropagating surface states may arise. These states result in a sharp feature in the transmission and reflection spectra of the system. We also show that(More)
We demonstrate that microscale tailoring of surfaces of magnetophotonic crystals provides an approach to engineer responses of known materials. In particular, we study states that are spatially localized at the interface between magnetophotonic and photonic crystals. Such states are an optical analog of the Tamm states long known in solid-state physics. The(More)
We demonstrate the existence of a spectrally narrow localized surface state, the so-called optical Tamm state, at the interface between one-dimensional magnetophotonic and nonmagnetic photonic crystals. The state is spectrally located inside the photonic band gaps of each of the photonic crystals comprising this magnetophotonic structure. This state is(More)
We study surface Tamm states in magnetophotonic structures magnetized in the Cotton–Mouton ͑Voigt͒ geometry. We demonstrate that the periodicity violation due to the structure truncation together with the violation of the time reversal symmetry due to the presence of magneto-optical materials gives rise to nonreciprocality of the surface modes.

The Springer Series in Materials Science covers the complete spectrum of materials physics, including fundamental principles, physical properties, materials theory and design. Recognizing the increasing importance of materials science in future device technologies, the book titles in this series reflect the state-of-the-art in understanding and controlling(More)
Magnonics is an emerging field dealing with ultralow power consumption logic circuits, in which the flow of spin waves, rather than electric charges, transmits and processes information. Waves, including spin waves, excel at encoding information via their phase using interference. This enables a number of inputs to be processed in one device, which offers(More)
SUMMARY Experimental and theoretical studies of light coupling to various magnetic nanostructured media and nanocomposites are briefly reported. Enhancement of the magneto-optical response is shown to occur when the constitutive materials of photonic crystals are magnetic. Transmission and reflection types of 1D magnetophotonic crystals (MPCs) have been(More)
