High thermal conductivity Gallium Gadolinium Garnet Single Crystal Substrates

High thermal conductivity GGG Single Crystal Substrates

1.Introduction:

GGG substrate, Gadolinium gallium garnet (GGG) has good physical and mechanical properties and chemical stability. It is the best substrate material for made microwave isolators. 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. GGG single crystal substrates of different tangential, which can achieve the best lattice match with these magneto-optical materials, Thus ensuring the YIG, BIG film epitaxial growth be successful.

2.Main Advantages :

• Low optical losses (<0.1%/cm)

• High thermal conductivity (7.4W m-1K-1).

• High laser damage threshold (>1GW/cm2)
