TriLumina Corp of Albuquerque, NM, USA, which develops flip-chip vertical-cavity surface-emitting laser (VCSEL) array light sources for automotive, consumer and industrial 3D sensing and interior illumination products, has completed all required tests for AEC-Q102 Grade 1 operation, which means it can reliably operate at temperatures ranging from -40°C to 125°C. This is said to be the first time that any semiconductor laser product has qualified for AEC-Q102 Grade 1 operation.
The Automotive Electronics Council (AEC) determines the prerequisites that are necessary to be accepted by tier-1 automotive electronics manufacturers. One is compliance with the applicable AEC-Q reliability standards; the other is compliance with IATF 16949 specifications (Quality Management System) of Zero-Defect supply chain quality management standards. The reliability test of automotive integrated circuits (AEC-Q) is broken down into several subcategories, of which AEC-Q102 (Discrete Optoelectronics) is the applicable standard for TriLumina’s VCSEL products.
TriLumina’s patented back-emitting VCSEL arrays with optional integrated microlenses are used in solid-state direct ‘Flash’ LiDAR (light detection and ranging), time-of-flight (ToF) LiDAR, scanning LiDAR and automotive in-cabin systems with full performance from -40°C to 125°C without need for active cooling.
“We design our products from the ground up to perform reliably over wide temperature ranges in extremely rigorous automotive operating conditions,” says president & CEO Brian Wong. “Having the first AEC-Q102 Grade 1 qualified VCSEL product in the industry proves just that.”
AEC-Q102 Grade 1 qualification also means that the devices are very robust for consumer and industrial applications exceeding the quality requirements for those market segments.
