In recent years, 3D sensing facial recognition has become a highly sought-after new feature in the industry. Under this trend, global smartphone manufacturers, as **representatives of the industry**, will inevitably accelerate the adoption of 3D sensing technology, making it highly likely to become a standard feature of smartphones within the next five years. In the application of gesture recognition and 3D sensing technology in consumer electronics, VCSEL will continue to gain broader adoption.

High-power VCSEL chips need to be packaged on highly thermally conductive aluminum nitride ceramic substrates to achieve functions such as mechanical support, vertical electrical connection (insulation), efficient heat dissipation, and auxiliary light emission. Although the market for VCSEL lasers in the consumer electronics sector is just emerging, they have already been widely applied in fields such as optical communication, optical interconnection, laser fuzing, laser display, and optical signal processing. Many familiar application scenarios, such as three-dimensional information, three-dimensional recognition, gesture recognition, iris recognition, and information transmission like autonomous driving radar, are all realized through this technology.

Medical diagnosis and treatment applications in the healthcare sector are also growth points for the VCSEL market. For example, in optical nerve stimulation and computed radiography imaging applications, VCSELs offer superior electrical efficiency compared to LEDs, a advantage that will drive their increased use in short-range sensing.

In the military domain, it also plays a dominant role in the near-infrared band, such as high-power illumination for perimeter and border security, imaging through smoke and explosions, as well as remote surveillance and satellite imaging systems.

With the rapid increase and gradual popularization of new applications such as gesture recognition, data storage, and surveillance monitoring, the rapid growth of VCSEL will inevitably drive the application and adoption of aluminum nitride materials.
