Product Description
Gadolinium Gallium Garnet (GGG) Single Crystal Substrate
Gadolinium Gallium Garnet (GGG, Gd₃Ga₅O₁₂) is a premium magneto-optical and microwave substrate material. It serves as the optimal substrate for infrared optical isolators operating at 1.3μm and 1.5μm wavelengths, which are critical components in optical communication systems. GGG substrates are essential for fabricating YIG and BIG films combined with birefringence components, making them indispensable for advanced microwave isolators and related devices.
Key Performance Advantages
- Large dimensions ranging from 2.8mm to 76mm diameter
- Exceptionally low optical losses (
