Copper-doped Lithium Niobate (Cu:LiNbO3) is a type of lithium niobate crystal with a small amount of copper (Cu) ions substituted for lithium ions. The addition of copper ions affects the optical and electronic properties of the crystal, making it useful for various photonic and optoelectronic applications.
Cu:LiNbO3 is known for its high nonlinear optical coefficients, making it useful for frequency conversion and other nonlinear optical processes. It is also widely used as a modulator material in optical communication systems. In addition, the piezoelectric properties of Cu:LiNbO3 allow it to be used for transducer applications.
The combination of the nonlinear, piezoelectric, and optical properties of Cu:LiNbO3 make it a versatile and valuable material in the field of photonics and optoelectronics.
