Smartphone features to fuel VCSEL growth, says Yole: Page 3 of 3

June 26, 2019 //By Julien Happich
The global VCSEL market should surpass US$3.7 billion by 2024, growing at a 31% CAGR between 2018 and 2024, according to Yole Développement’s latest estimates.

After Apple, Xiaomi and Oppo released their flagship phones with a 3D sensing feature, and even more recently the two market leaders, Huawei and Samsung, began implementing VCSELs. On the technology side, structured light, which was used for facial recognition for the first time on high-end smartphones, implies the use of two different VCSELs: one flood illuminator and one dot projector.

Using these two light sources adds a tangible cost to the 3D sensing module.
Meanwhile, a face recognition module using the ToF principle was implemented by LG in early 2019. This leads to using only one VCSEL, a flood illuminator, and therefore a reduced cost of the 3D sensing module compared to modules using the structured light principle.
The VCSEL comparative review, conducted by System Plus Consulting provides insights into the structures, technology, and design choices related to these components, at the center of innovative functions for smartphones. The report proposes a technical & economic comparison of 10 VCSEL dies integrated by the major smartphone manufacturers: Apple, Xiaomi, Huawei, Oppo, and Lenovo in their flagship smartphones, and by Intel in its RealSense product suite.
