Our optical grade undoped Czochralski grew Gadolinium Gallium Garnet Crystal Substrates with high optical homogeneity excluding central core of crystal boules, without visible striae with shadowgraph, inclusions and bubbles.
Gadolinium gallium garnet (GGG) is a dedicated substrate for the 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. Gadolinium Gallium Garnet Crystal Substrates of different tangential, which can achieve the best lattice match with this magneto-optical material, thus ensuring the YIG, BIG film epitaxial growth be successful.
GGG Crystal Substrates have good physical and mechanical properties and chemical stability; it is the best substrate material for making the microwave isolators.
