Abstract: With the rapid explosion of 3D sensing, VCSEL has entered the consumer electronics field from the optical communication field. The application of VCSEL market in many scenarios also shows its infinite potential. Smartphone brands in China have begun to integrate 3D sensing technology and have launched supply chain alliances and cooperation. In this paper, the global patent distribution of VCSEL is analyzed from multiple perspectives.Some suggestions are put forward to promote the construction of intellectual property rights in the field of optical devices in China, and suggestions are made to promote the overall development of the optical device industry in China.

Key words: vertical cavity surface emission laser, patent, distribution
