Preparation of magnetophotonic crystals with ND-controlled EB-evaporation method and their large enhancement of Faraday effect

Abstract The potential of one-dimensional magnetophotonic crystals (1D MPCs) were investigated in theoretical and experimental studies. We prepared 1D MPC of (Ta 2 O 5 /SiO 2 ) 9 /Bi:YIG/(SiO 2 /Ta 2 O 5 ) 9 and (Si/SiO 2 ) 3 /Bi:YIG/(SiO 2 /Si) 3 utilizing the dielectric layer formed by using the ND-controlled EB evaporation method. We obtained basic magneto-optical properties that were in agreement with 1D MPC predicted theoretically. θ F of the multilayer structure was more than 150 times larger than that of a Bi:YIG single-layer film.
