Gadolinium Gallium Garnet (GGG) Single Crystal Substrate for YIG and BIG Film

Gadolinium Gallium Garnet (GGG, Gd3Ga5O12) is a magneto-optical and microwave substrate. It is the best substrate material for infrared optical isolator (1.3 and 1.5um), which is a very important device in optical communication. It is made of YIG or BIG film on the GGG substrate plus birefringence parts. Also GGG is an important substrate for microwave isolator and other devices. Its physical, mechanical and chemical properties are all good for the above applications.


Main Advantages:

  • Large dimensions,from 2.8 to 76mm.
  • Low optical losses (<0.1%/cm)
  • High thermal conductivity (7.4W m-1K-1).
  • High laser damage threshold (>1GW/cm2)
