Multistep staircase avalanche photodiodes with extremely low noise & deterministic amplification (lidar)

Engineers at University of Texas at Austin and University of Virginia developed a light detector that can amplify weak light signals and reduce noise to improve the accuracy of lidar.

Through a combination of co... » read more
