YIG
YIG has superior optical and microwave properties. In the field of optics, the Faraday effect of yttrium iron garnet can be used to manufacture mid-infrared isolators, laser modulators, fiber optic current sensors and other products; In the field of microwaves, YIG has high Q resonance characteristics, which can be used to manufacture magnetic resonance filters, tuned oscillators, bandpass filters and other products. Currently, YIG single crystals are mostly used among the wavelength of 2000-4000nm.
