Why Lithium Nioabate Wafers?

Recently Lithium Niobate (LiNbO3) substrates are increasingly used to fabricate integrated optical devices.  By reducing waveguide dimensions, LiNbO3 electro-optical modulators can create new design paradigms that enable a wide range of applications, such as drive voltage and the expansion of the spectrum of nonlinear optical applications for high-performance optics.

Increasing demand for optical-fiber-based communication systems will increase the demand for LiNbO3 modulators.
LiNbO3 applications include Q-switching devices, high-performance gyroscope, accelerators and accelerometer sensors as well as MEMS devices

What Are The Different Cuts, (X,Y,Z, etc.) and what the differences is between SSP and DSP?

  1. first, the price of one piece of "LiNbO3 SAW grade, Y-cut, 10x10x0.5mm, SSP " is $Contact Us
  2. Taking LN wafer as an example, the Y plane is the polar plane and hydrofluoric acid is used for wet etching.
    The corrosion rate of front and back of the wafer is different.The Angle (0°, 90°, 90°) means that the -Y side
    of the wafer is the polished surface, and there is a reference edge on the +Z end of the wafer.The Angle (180°, 90°, 90°)
    indicates that the +Y side of the wafer is the polished surface and that the reference edge is still on the +Z end of the wafer.
    please refer to the following picture shows:

Also, DSP means double sides polished, and SSP means single side polished and the other side usually lapped with Ra around 0.2-0.5um.
