<111> Orientation Gallium Gadolinium Garnet Single Crystal Substrates
GGG single crystal substrates of different tangential,which can achieve the best lattice match with this magento-optical material,thus ensuring the YIG,BIG film epitaxial growth be successful.It has good physical and mechanical properties and chemical stability.
GGG is also substrate material for microwave devices.
In the optical communication devices,require a lot of using 1.3u and 1.5u optical isolator,which core component is the YIG or BIG film been placed in a magnetic field.
