Band structure and Bloch states in birefringent one-dimensional magnetophotonic crystals: an analytical approach

Abstract

An analytical formulation for the band structure and Bloch modes in elliptically birefringent magnetophotonic crystals is presented. The model incorporates both the effects of gyrotropy and linear birefringence generally present in magneto-optic thin film devices. Full analytical expressions are obtained for the dispersion relation and Bloch modes in a layered stack photonic crystal and their properties are analyzed. It is shown that other models recently discussed in the literature are contained as special limiting cases of the formulation presented herein.

One-dimensional photonic crystal with a complex defect containing an ultrathin superconducting sublayer

“…Nevertheless, such unconventional constituents for PCs as magnetic and ferroelectric materials were investigated as well. [4][5][6][7][8][9][10][11][12][13][14] Another group of unconventional materials for PCs, namely, superconductors was also studied in a number of theoretical publications for 1D and 2D PCs. [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] All the articles related to superconducting ͑SC͒ PCs were investigating regular ͑nondefect͒ structures.…”

“…The thicknesses of magnetic and nonmagnetic materials are d 1 and d 2 , respectively. The NLC is characterized by a longrange uniaxial orientational order of rod-like anisotropic molecules along a common director, whose dielectric tensor is given by [86] ( 19) www.intechopen.com where α is the tilt angle between the principal axis of NLC molecule and the x axis. Δε is the optical dielectric anisotropy given as , n 0 and n e are ordinary and extraordinary refractive indices, respectively.…”

Absorption suppression in photonic crystals

“…The electric conductivity σ is included in the definition (3) of the respective permittivity tensorε F , as specified in (4). In all cases, the incident wave Ψ I propagates along the z direction normal to the layers and has linear polarization with E I x.…”

“…In comparison to uniform magnetic materials, magnetic photonic crystals can display much stronger nonreciprocal properties, such as magnetic Faraday rotation [1,2,3,4,5,6,7,8,9]. Strong nonreciprocal effects are essential in isolators, circulators, and other microwave and optical devices.…”
