Photonics Could Reduce The Cost Of Lidar
By Karen Heyman - 05 Sep, 2024 - Comments: 0

Using light to move data over shorter distances is becoming more common, both because there is much more data to move around and because photons are faster and cooler than electrons. Using optical fiber for mission-critical communication is already well established. It has been the preferred PHY for long-haul communications for decades because it doesn’t suffer from the attenuation losses ... » read more
