Product Description
Substituted Gadolinium Gallium Garnet (GSGG) Single Crystal Wafer
Substituted Gadolinium Gallium Garnet (GSGG) is a specialized substrate material for magneto-optical films. In optical communication equipment, numerous 1.3 and 1.5 micron optical isolators require YIG or BIG films placed in magnetic fields. GSGG single crystal substrates provide optimal lattice matching with these magneto-optical materials, ensuring successful epitaxial growth of YIG and BIG films.
