Gadolinium Gallium Garnet (GGG) is a special substrates used in magneto-optical film. In optical communication equipment, YIG or BIG films placed in a magnetic field are core components in the optical isolators. Different tangential GGG single crystal substrates can be matched with the crystal lattice of such magneto-optical materials to ensure the good epitaxial growth of YIG and BIG films. GGG is also a substrate material for making microwave isolators.
