3 Inches Gadolinium Gallium Garnet GGG Crystal Substrates Wafer
Diameter 3 Inches Gadolinium Gallium Garnet (GGG) Crystal Substrates Wafer
3 inches Gadolinium Gallium Garnet (GGG) Crystal Substrates Wafer
Introduction:
Gadolinium gallium garnet (GGG) is used for a magneto-optical film (YIG thin film or BIG) a special substrate in the optical communication apparatus, YIG or BIG films are 1.3 and 1.5 of the optical isolator core components of different crystal orientation GGG single-crystal substrate may have the best film with such lattice matching .
Crystro can provide GGG substrates with a diameter of 4 inches. GGG substrates have good physical, mechanical properties, and chemical stability, so as to ensure the success of the epitaxial growth film.
Applications :
-
Magneto-optical films (such as YIG or BIG thin film)
-
High–temperature superconductors substrate
-
optical isolator
