GGG substrate, Gadolinium gallium garnet (GGG) is dedicated substrates for magneto-optical film. In the optical communication devices, require a lot of using 1.3μ and 1.5μ optical isolator, Its core component is the YIG or BIG film been placed in a magnetic field. GGG single crystal substrates of different tangential, which can achieve the best lattice match with these magneto-optical material, Thus ensuring the YIG, BIG film epitaxial growth be successful.
GGG have good physical and mechanical properties and chemical stability. GGG is the best substrate material for made the microwave isolators .
