Why does Zhongke Guangxin keep a low profile?

The core epitaxy technology of optical chips is not mature. The self-developed chip technology lags behind developed countries, the core technology is still in the research and development stage, and the existing high-end technology lags behind developed countries. Zhongke Optical Core is the only manufacturer in China that can independently produce optical chips in the whole production chain. On the whole, domestic optical chip manufacturers generally have the back-end processing ability except wafer epitaxy, but the epitaxial technology of optical chip core is not mature. The core technology of the chip is still in developed countries in Europe and America, and high-end epitaxial wafers need to be purchased from international epitaxial factories, which limits the development of high-end optical chips.
