On January 13, China`s leading VCSEL optical chip technology company, SZBS Optoelectronics Technology, announced that SZBS has recently completed 300 million yuan in round B and B+ rounds of financing.
SZBS is a semiconductor laser chip developer, whose main business is the design and development of VCSEL (vertical cavity surface emitting laser) laser chips.
The company already possesses VCSEL chip design, epitaxy, oxidation and other core process capabilities, and has reached VCSEL mass production conditions.
The VCSEL chip is the core device of the 3D sensing system and is at the top of the industry pyramid. According to industry media, VCSELs have advantages in power consumption, volume, accuracy, and reliability compared to semiconductor light sources such as LEDs and EELs (edge emitting lasers).
The chip can be used in many scenarios, such as mobile phone 3D face recognition, offline face payment, mobile consumer AR, gesture operation, etc. The coverage areas include AR/VR, smart home, smart security and other fields.
In 2017, Apple used the 3D sensor with VCSEL as the core device for face recognition in iPhone X for the first time. The application of 3D sensor in emerging fields such as living body detection, iris recognition, AR/VR technology, and autonomous driving assistance technology has also begun. Arouse market attention.
However, VCSEL chip manufacturing is difficult. In the early stage, only a few overseas companies such as Finisar, Lumentum, AMS, and Sumitomo Electric have produced energy production. However, since the first half of 2018, many VCSEL chip technology companies in China have completed financing, except for SZBS. There are also companies such as JSZH Optoelectronics Technology Company, SZCG Optical Core Technology Group, SZJZ Optoelectronics Technology Company, and NBRX Optoelectronics Technology Company.
