Abstract

We report the properties of one-dimensional heteroepitaxial all-garnet magneto-optical photonic crystals (MOPCs) composed of alternating quarter-wavelength layers of diamagnetic Sm 3 Ga 5 O 12 and MO-active Bi 2.97 Er 0.03 Al 0.5 Ga 0.5 O 12 garnets rf-magnetron sputtered on Gd 3 Ga 5 O 12 ( 111 ) substrate. Substitution of ferric ions by aluminum and gallium improved transparency and induced perpendicular anisotropy in pure bismuth iron garnet. As a result, photonic crystals owned a record high magneto-optical quality and a latching-type (magnetic remnant) Faraday rotation (FR). At the resonance wavelengths 775 ( 640 ) nm , a specific FR θ F = 14.1 ( 14.8 ) deg / μm and MO-quality factor Q = 99.3 ( 46.2 ) deg represent the highest MOPC performance achieved so far.
