Excelitas Technologies’ pulsed laser diode array advances LiDAR design
Autonomous Vehicle Technology announces 2019 ACES Award Winner in Autonomy | Sensors
The rise of autonomy and the integration of LiDAR into automotive applications is pushing the boundaries technology, especially of LiDAR sensor, emitter, and package design. The new generation of optoelectronic components and modules must deliver high levels of reliability in high-volume, cost-effective packaging to meet the demands of the autonomous-vehicle market.
Excelitas Technologies’ innovative SMD (surface mount device) 905nm 1X4 Pulsed Laser Diode Array has delivered just that—a re-engineered, consumer-grade laser array to enable the design of more efficient, longer range, and lower cost LiDAR systems. The customizable laser array addresses OEM design engineers’ needs by combining field-proven high-efficiency, multi-cavity laser chip technology with small form-factor surface mount device packaging. Unlike single-pixel lasers, the 1X4 linear configuration allows each pixel to be situated in close proximity to its neighbor, minimizing space requirements in the assembly and enabling the use of smaller, less costly optical components.
The array is fully compatible with SMD pick-and-place and reflow soldering equipment, allowing it to seamlessly integrate into high-volume, low-cost assembly lines. Each laser pixel can have up to four emitting stripes, enabling very high per-channel optical power levels in excess of 85 W for longrange detection with minimal power consumption.
