Problem
Current InGaAs avalanche photodiodes (APDs) used in LiDAR, range finders, and optical fiber testing often lack the sensitivity needed for optimal performance, limiting detection range and requiring more complex and costly system designs. These limitations hinder the development of smaller, more efficient infrared systems.
Solution
Phlux developed Aura Noiseless InGaAs® APDs that offer significantly enhanced sensitivity compared to traditional APDs. These sensors achieve up to 12 times higher sensitivity, enabling up to 50% greater detection range in applications such as LiDAR and optical fiber testing. By improving sensitivity, Aura APDs reduce the need for additional optical components and simplify thermal management, leading to smaller, more cost-effective system designs. The sensors are designed as drop-in replacements for existing components, facilitating easy integration into current systems.
Target Audience
The primary target audience includes manufacturers of LiDAR systems, laser range finders, and optical fiber test equipment (OTDRs) seeking to improve the performance and reduce the cost of their infrared systems.
