Kyocera has developed underwater optical communications technology that enables high-speed wireless communication at speeds up to 5.2 Gbps in freshwater settings, significantly faster than traditional underwater acoustic systems. This advancement is crucial for underwater drone technologies, allowing for data streaming of high-resolution photos, live video feeds, and sensor data. While limited to short distances of around 100 meters due to water's impact on laser range and line-of-sight requirements, the technology offers high speed, bandwidth, and low latency, making it suitable for specific applications like controlling underwater drones and monitoring undersea infrastructure. Additionally, it could have military applications for communicating with underwater drones launched from submarines or larger vessels.

Silanna Delivers Industry’s Smallest Laser Firing System ICs

Silanna Semiconductor has introduced the SL2001 and SL2002 laser firing system ICs for LiDAR and rangefinders, offering a significant reduction in power consumption, system size, BOM cost, and design complexity compared to other laser driver technologies. These ICs combine resonant capacitor charging and high-current laser diode firing on a single chip, reducing a laser system's footprint by 80%. The SL2001 is designed for automotive-grade LiDAR, delivering sub-2-ns laser pulses with a peak power output of 1,000 W, while the SL2002 is suitable for handheld systems with a 100-W pulse. Both ICs are housed in a compact 14-pin, 3.5-mm2 package and can be used with various laser types.
