Substituted Gadolinium gallium garnet GSGG Single Crystal Wafer
Substituted Gadolinium gallium garnet(GGG) is a special substrate
magneto optical flims. In optical commuication equipment, a large
number of 1.3 and 1.5 micron optical isolators are needed, and the
core component is YIG or BIG film placed in the magnetic field.
Different tangential GGG single crystal substrates can be matched
with the lattice of such magneto-optical materials, thus ensuring
the successful epitaxial growth of YIG and BIG films.
