Thermal management optimization in high-power 3D sensing VCSELs

Published in: SPIE LASE 2022 Authors: A. Filipchuk, K. Nechay, R. Ulkuniemi, S. Talmila, P. Uusimaa  Published in: SPIE LASE 2022 Authors: A. Filipchuk, K. Nechay, R. Ulkuniemi, S. Talmila, P. Uusimaa Vertical-cavity surface-emitting lasers (VCSELs) have recently paved their way into the 3D sensing market, specifically in mobile device applications. Vertical emission of VCSELs enables arranging single emitters into high-power 2D arrays. Thus, VCSEL arrays require efficient heat management which can be implemented by the means of packaging, both to improve thermal conductivity and to keep VCSEL chips intact. This becomes particularly important when considering also very high-density laser arrays and 2D matrices for quantum Continue reading →

Eye-safe laser illuminators for long-reach LIDAR and gated imaging in harsh weather conditions

Published in: SPIE LASE 2021 Authors: Lasse Orsila, Visa Kaivosoja, Petri Melanen, Petteri Uusimaa  Published in: SPIE LASE 2021 Authors: Lasse Orsila, Visa Kaivosoja, Petri Melanen, Petteri Uusimaa Autonomous driving and automated ships are in increasing demand and the performance for pattern recognition and safety functions are essential. Harsh weather conditions lower the atmospheric transmission for useable eye-safe wavelengths and water vapor peaks prevent most laser light propagation for longer distances. In LIDAR application this problem can be solved with increased peak power. However, high peak power solutions with high repetition rate do not exist or they are bulky and Continue reading →

Long-range all-solid-state flash LiDAR sensor for autonomous driving

Published in: SPIE LASE 2021 Authors: Juha Lemmetti, Niklas Sorri, Ilkka Kallioniemi, Petri Melanen, Petteri Uusimaa  Published in: SPIE LASE 2021 Authors: Juha Lemmetti, Niklas Sorri, Ilkka Kallioniemi, Petri Melanen, Petteri Uusimaa LiDAR sensors have gathered lot of interest in the field of autonomous driving. Still, the offering of mass-produced, small form-factor all-solid-state LiDAR sensors remain scarce. Furthermore, most of the sensor applications are currently designed for short-range (<50 feet) and medium-range (50-300 feet) applications. There’s a requirement for an efficient solution for long range LiDAR sensor that can be used to monitor the road in front of the vehicle. It must Continue reading →
