Product Details

Fe doped Lithium Niobate Wafer Optical Grade and SAW Grade

Lithium Niobate (LiNbO3) is a useful optoelectronic material. The material not only has unique piezoelectric, optical and photoelastic properties, but also has good mechanical and chemical stability. Its combination of excellent electro-optic, acoustooptic and nonlinear optical properties makes it an attractive material in integrated optics.

BonTek provides up to 6" diameter LN doped wafers: Er:LN, MgO:LN and Fe:LN. The most used SAW orientations are YZ-cut and 128°Y-cut. The 128°Y-cut with X propagation is said to have the lowest spurious signal level.

FAQs:

Q: What are the products you mainly work on?

A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.

Q: Can you accept product customization?

A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.

Acceptance Check
