TriLumina to Collaborate with ADI on Creating VCSEL Module for LiDAR

TriLumina Corp. of Albuquerque, New Mexico USA announced a collaboration with Analog Devices, Inc. (ADI) for producing a new integrated, solid-state illuminator module for automotive FLASH LiDAR systems. The company intends to integrate TriLumina’s Vertical Cavity Surface Emitting Laser (VCSEL) array laser emitters with ADI’s patent pending high-speed pulse laser driver.

ADI’s boasts that its pulse laser driver enables high optical power output from a single, small surface mount IC package.

According to TriLumina, the combination marks a milestone towards cost-effective, high-performance LiDAR systems. TriLumina says its collaboration with ADI signals will make it an integral player in next generation automotive LiDAR systems. LiDAR will be essential for advanced driver assistance systems (ADAS) and Autonomous Driving Vehicles (ADVs) of the future.

LiDAR uses pulsed lasers and sensors that bounce lasers off of other vehicles and objects to continuously calculate the distance to the other vehicle or object. The scan of the object creates a digital map that both helps with cameras for object recognition and with radar for distance measurement.

Current Lidar systems tend to have issues of bulky mechanical size, low reliability, and high cost. TriLumina says that the new system that the companies plan to create will help overcome these issues.

“TriLumina offers unique illumination devices based on solid-state, back-emitting, flip-chip VCSEL arrays.  When coupled with ADI’s driver technology, these lasers provide higher optical power, enabling FLASH LiDAR systems to achieve greater range,” stated Brian Wong, TriLumina’s CEO.

“We are excited to work with TriLumina on a power efficient, small footprint LiDAR illuminator,” said Chris Jacobs, general manager, Automotive Safety Group, Analog Devices. “LiDAR is a key pillar of ADI’s automotive safety strategy along with RADAR and inertial sensors. It will become a critical element of safety systems as functions such as Automatic Emergency Braking (AEB) and autonomous driving become more common.”
