Comparative investigation of 1D photonic crystal of magneto-optical and electro-optical materials with a nanocomposite of three/four-phase mixtures

The present work reveals comparative optical properties of 1D photonic crystals consisting of magneto-optical and dielectric layers with the defect layer of electro-optical material sandwiched with two nanocomposites designed of three-phase and four-phase compositions; ITO/TiO 2 /air and ITO/TiO 2 /graphite/air. As magneto-optical and electro-optical materials, cerium-substituted yttrium iron garnet and lithium niobate are used to design 1D photonic crystals to study field-dependent properties. The considered anisotropic magneto-optical and electro-optical material have magnetic and voltage-dependent dielectric properties, respectively, therefore, the effect on hybrid modes or Tamm plasmons polaritons modes, as well as transmission, reflection, Faraday rotation ( θ F ∘ ) and ellipticity ( ϕ ∘ ) angles, are discussed with 4 × 4 Transfer Matrix method. In this work, we explain the tunable optical properties of 1D photonic crystal including Faraday rotation and ellipticity with varying distinct parameters. With the optimized parameters, the proposed 1D photonic crystal might be used for tunable electro-optical and magneto-optical devices such as filters, switches, modulators, etc.
