1. Jinan Zheng Jing Electronic Technology Co., Ltd.: Jinan Zheng Jing Electronic Technology Co., Ltd. was established on 20 10, and is committed to the industrial production of photoelectric and piezoelectric single crystal thin film materials with nano-micron thickness. It is the first in the world to develop and industrialize lithium niobate single crystal thin film materials with a thickness of 300 to 900 nanometers. Many excellent research results of thin film lithium niobate at home and abroad are based on its wafer products.
2. Shanghai New Silicon Polymeric Semiconductor Co., Ltd.: Established in February, 2020, located in Jiading District, Shanghai, China, led by Dr. Haigui's team and funded by all investors, it is a high-tech enterprise dedicated to R&D, production and sales of heterogeneous integrated material substrates.
3. Xiamen Webb New Materials Co., Ltd.: It is an enterprise registered in Hong Kong with the registration number 1990. Its product business covers GaN wafers, SiC wafers, GaAs wafers, compound semiconductors, germanium wafers, CdZnTe wafers, silicon wafers and LNOI wafers.
4. Tiantong Holdings: Lithium niobate single crystal film (material of 800G optical module) is lithium niobate crystal material. Tiantong Holding Co., Ltd. started the production and research and development of lithium niobate and lithium tantalate crystals from 20 16, and is currently in a leading position in technology and capacity in the domestic market.
Application of lithium niobate thin film
As the basic material of industrial chain, this product is mainly used in the following fields:
1, optical fiber communication, such as waveguide modulator. Compared with traditional products, the device made of this thin film material can be reduced by more than one million times, the integration level is greatly improved, the response frequency is wide, the power consumption is low, the performance is more stable, and the manufacturing cost is reduced.
2. Electronic devices, such as high-quality filters, delay lines, surface acoustic waves, electro-optical modulation, laser Q-switching, optical gyroscopes, optical parametric oscillation, optical parametric amplification and other devices.
3. In the field of information storage, high-density information storage can be realized, and the information storage capacity of a 3-inch film is 70T (equivalent to 65,438+one million CDs).
