LEMON Photonics recently launched the world's leading multi-junction addressable VCSEL laser chip, integrated wide area, high power, long distance, low power, anti-interference, customized design and other advantages, which greatly enriched and met the miniaturization of various smart devices such as LiDAR, laser lighting and other application.
Multi-junction addressable VCSEL LIDAR application
The development direction of Optical system integration is miniaturization, fast sensing, low power consumption and high power. Traditional VCSEL lasers use a single chip coupled with optics to illuminate different locations of the target, thereby reducing the size limitations of the detector array and the reflection of light sources in high-reflectivity areas, and the optical design is complex. LEMON Photonics' newly developed 905nm and 940nm multi-junction addressable VCSEL chip designs solve the industry pain points of package miniaturization requirements for optical integrators and further provide optical performance.
DToF technology has been an indispensable technology in LiDAR and 3D sensing functions. With the continuous expansion of application scenarios, the original popular single point dToF has been unable to meet the needs of users. LEMON Photonics multi-junction addressable VCSEL chip can realize the zoning lighting, adjust the control signal strength of each area, improve the overall work efficiency and reduce the redundant laser, and reduce the power consumption. Multi-junction addressable VCSEL enables more flexible lattice plots to be constructed for advanced 3D structured light algorithms. Achieve greater distance detection and reduce ambient light interference.
LEMON Photonics multi-junction addressable VCSEL configuration is divided into 64x1, 32x1, 16x1 regions or 2x2, 4x2, 4x4 regions. Each zone can individually control the work, measure the distance, and each mode can flexibly control the FOV and focus areas depending on the application. LEMON Photonics can be customized according to customer needs.

The innovation of multi-junction addressable VCSEL technology further improves the working efficiency, peak power and pulse rise time of the laser. Due to the strong economic demand in the consumer, industrial and automotive markets, the VCSEL is bound to shine in the LiDAR, high-end consumer electronics, TOF modules, infrared lighting, ADAS and other markets.
