2. VCSEL Chip Classification

VCSEL chips can be divided into PS (proximity sensors) series, TOF (time-of-light) series, and structured light series according to application:
PS series VCSEL: A low-power VCSEL chip that can be used in the field of proximity sensors, replacing traditional LED light sources. Its application areas include short distance sensing, 3D sensing, biomedical, and more.
TOF series VCSEL: Restores the 3D shape of light source illumination through time-of-flight sensing technology (D-TOF, i-TOF), with applications in robotics, LiDAR, projection, AR/VR, and more.
Structured light series VCSEL: Structured light VCSEL laser, which analyzes the deformation of the reflected light spot of the illuminated object, calculates the distance, shape and other information of the object, and its application fields include face recognition, access control, etc.

VCSEL has advantages such as high efficiency, good beam quality, high accuracy, low power consumption, miniaturization, high reliability, fast modulation rate, mass production capability, and low manufacturing cost. It is the core component of modules such as LiDAR and 3D sensing, and will become an essential component in the next wave of high-tech mainstream.

VCSEL relies on the consumer market and continuously explores new markets through its own technological development. With the commercial landing of cutting-edge VCSEL technologies and the maturity of VCSEL’s mass production stability, VCSEL has found new roles and gradually established itself in emerging markets such as medical aesthetics, automotive applications, and AR, becoming an irreplaceable core light source device.
