\u3000\u30001. The penetration speed of laser application field is accelerated, the scope is wider, and the market ceiling is constantly rising: with the gradual localization of upstream core optical chips, the application cost of laser is gradually reduced, and the laser will penetrate into many industries more deeply. It is expected that the application field of laser processing will be further expanded and the market scale will be further expanded in the future. It will be more applied to many fields such as automobile, consumer electronics, optical communication and national defense scientific research. As the core device or component of the above laser applications, semiconductor lasers will also obtain rapid development space.
2. There is huge room for localization and substitution of high-end products: compared with developed countries in Europe and the United States, China still has a large gap in the application of laser technology and high-end core technology, especially the core components such as upstream semiconductor laser chips still rely on imports. The technical threshold of high-end optical chips is high, and the localization rate of China's core optical chips is low, which mainly depends on imports. Chinese enterprises begin to test and verify China's optical chip products and seek localization substitution, which will promote the process of localization of the optical chip industry.
3. High power, 25g and above, high bandwidth, narrow linewidth and other high-end products are expected to benefit from domestic alternative related industrial targets. Among them: high power representative: Changguang Huaxin; High bandwidth representatives: Yuanjie technology, Accelink Technologies Co.Ltd(002281) , Guangwei Technology (chirp suppression 25gdml), guang'anlun, Minxin, Yunling optoelectronics, Zhongke optical core, etc; Narrow linewidth: Micro source photons, etc; VCSEL laser: changguanghuaxin, zonghuixin, Bosheng optoelectronics, Huaxin semiconductor, Qianmu laser, etc.
In addition, the detector focuses on array technologies such as SPAD and SIPM. The targets of relevant industrial chains are mainly start-ups, including parity electronics, core vision, Lingming photonics, Xinhui technology, flying core electronics, etc.
4. Viewpoint of communication sector
At present, the valuation of the communication sector has fallen to a historical low, the growth is determined, and under the environment of loose liquidity in China, communication and other industries have entered the value buying range. Recommended this week:
1) for undervalued and high dividend, telecom operators (a + H) with strong consumption attributes must be selected: China Mobile, China Telecom Corporation Limited(601728) , China United Network Communications Limited(600050) .
2) the main equipment, digital communication equipment, IDC, and IDC, the main equipment, digital communication equipment, IDC, and the light module sector that still underunderestimateunderestimatevalue growth is still growing. 2) the main equipment, data communication equipment, IDC, and the main equipment, data communication equipment, IDC, and the main equipment, data communication equipment, IDC, and the main equipment, data communication equipment, IDC, and the light module sector with the light module sector: 0000 Shenzhen Zhenye(Group)Co.Ltd(000006) Guangdong Tloong Technology Group Co.Ltd(300063) the.
3) high growth energy informatization sector: Longshine Technology Group Co.Ltd(300682) , Willfar Information Technology Co.Ltd(688100) etc.
4) other stocks: Guangzhou Haige Communications Group Incorporated Company(002465) (Beidou 3 penetration rate increased), Yealink Network Technology Co.Ltd(300628) , TCL Technology (panel price bottomed out), Tianjin 712 Communication & Broadcasting Co.Ltd(603712) (military informatization), Goldcard Smart Group Co.Ltd(300349) etc.
5. Risk warning: 5g demand continues to be lower than expected, and the operator's willingness to continue to invest decreases.
