The leader of photoelectric chip listed companies

The leading company of photoelectric chip listed company is Crystal Optoelectronics.

Optoelectronic chip listed company leading stock crystal optoelectronics. From 20 17 to 2020, the rate of return on total assets is divided into 8.47%, 8.85%, 8.27% and 6.63%. The leading manufacturer of optical photoelectric materials in China has formed a complete supply system of high-end optical resin, 3D imaging and mirror armor.

Because of the superior physical characteristics of light, optical cable is replacing cable in the field of communication; Optical chips have also begun to replace electrical chips to realize the transmission of optical signals on silicon-based materials. Optical module is an important device to realize the conversion of optical signals and electrical signals in optical communication system, which is composed of optical devices, functional circuits and optical interfaces. At present, the industrialization of optical chips/modules is still in the early stage. China 100% of high-end optical chips still rely on imports, and the lack of domestic optical chips has brought great development opportunities to the industry.

1. China optical chip listed companies are as follows:
