Understanding lithium niobate crystals

With the establishment of "new infrastructure" in recent years, 5g has gradually entered social life, and the channels of big data, VR technology, communication network and video broadcasting have also continued to grow. Promote the central optical grid to ultra-high speed and ultra long distance conduction, and in this link, a key component is indispensable - the lithium niobate mixer. Lithium niobate modulator is made by using the electro-optical effect of lithium niobate crystal and integrating the production process with photoelectric technology. It can convert the network format into light wave data and is an important component to ensure electro-optical switching. In detail, it is necessary to master the electro-optic phenomena and uses of its raw and auxiliary material lithium niobate crystal

lithium niobate crystal has two functions, especially eye-catching. First, lithium niobate crystal has many photoelectric effects, including thermoelectric effect, photoelectric phenomenon, nonlinear optical phenomenon, photorefractive reaction, photovoltaic effect, Elasto-optical effect, magneto-optical effect and other optical effects; Second, the effect of lithium niobate crystal can be controlled, which is formed by the crystal plane structure of lithium niobate crystal and a variety of disadvantages

in addition, the structural and mechanical properties of lithium niobate crystal are very stable, which is easy to manufacture, with wide light penetration region, large birefringence, and convenient to manufacture high-quality optical waveguides. Therefore, the optical modulator based on lithium niobate crystal has unique advantages in long-distance communication, and its stability is also very unique. Therefore, it is widely used in long-distance communication with high speed and high bandwidth
