Lithium niobate (LiNbO3) is a crystal material that OST Photonics utilizes to create wafers for photonic, piezoelectric, and electro-optic applications. These lithium niobate wafers, known for their high refractive index, piezoelectric properties, and nonlinear optical response, are integral to a wide range of applications, including telecommunications, sensing, and computing.
Lithium niobate wafers are thin, flat structures produced through processes such as crystal growth, slicing, and polishing. Researchers have extensively studied the photorefractive centers of LiNbO3 and related systems, with studies focusing on light-induced charge transport in pure LiNbO3, hexagonally-poled LiNbO3 for laser diodes, and the protonic conductivity of LiNbO3.
The LiNbO3 ring modulator is the first of its kind to demonstrate a large third-order intermodulation distortion spurious free dynamic range at 10 GHz and 1 GHz. Its linearity surpasses that of silicon ring modulators based on the plasma dispersion effect, making it an attractive material for compact modulators for analog optical links.
Lithium niobate has a refractive index of around 2.2, indicating that light traveling through the crystal will be bent by an angle determined by the refractive index of the material. The refractive index measures how much the speed of light is reduced when it passes through the material, with higher refractive indices bending light more than lower ones.
Integrated photonics involves integrating multiple photonic components onto a single platform, such as a thin film of lithium niobate. This technology enables the creation of compact, efficient, and high-performance photonic devices used in telecommunications, sensing, and computing.
Lithium niobate is a piezoelectric material, meaning it exhibits the piezoelectric effect. When a mechanical force is applied to lithium niobate, it produces a voltage, and when a voltage is applied, it produces a mechanical strain. These piezoelectric properties make lithium niobate useful in various applications, including pressure sensors, transducers, and actuators.
LiNbO3 is an excellent material for optoelectronic devices due to its unique piezoelectric and optical properties. Its mechanical stability makes it a desirable candidate for high-power SHG lasers. It is an excellent semiconductor for optical modulators and enables tunable IR outputs. It also exhibits outstanding spectral sensitivity.
LiNbO3 is also used for high-density storage. Its low density makes it an excellent material for lasers. It can be incorporated into various types of electronic components and used as a photonic crystal. The main advantage of LiNbO3 is its high refractive index.
Due to its strong piezoelectric properties, LiNbO3 is an ideal candidate for making ultra-high-power ultrasonic transducers for Enhanced Oil Recovery. This study demonstrates the effectiveness of LiNbO3 in reducing viscosity.
Due to its nonlinear optical properties, LiNbO3 is a good candidate for the second harmonic generator in a Nd:YAG laser. However, the low optical performance of LiNbO3 may limit its use in certain applications.
LiNbO3 wafers are also useful for acoustic wave-filtering. Its nonlinear polarization properties make it a suitable material for ultrahigh-frequency acoustic applications. Its low-frequency characteristics make it a good candidate for use in radio frequency.
The multifunctional crystal lithium niobate has numerous applications in photonics, electronics, and optoelectronics. Integrated photonics is becoming more widespread, and LiNbO3 has been found to be an excellent choice for this. Its ion-cut properties and low power consumption make it a valuable material for high-power, ultra-fast applications. OST Photonics is committed to providing high-quality lithium niobate wafers for various applications, contributing to the advancement of technology in various fields.
