Background IntroductionTwo dimensional materials have attracted widespread attention due to their atomic level thickness and unique properties, such as high binding energy, tunable bandgap, and new electronic degrees of freedom (valley electronics). They have many application prospects in fields such as microelectronics, nanophotonics, and nanoenergy. Various two-dimensional materials have their o...
LiDAR sensors are crucial for implementing modern technologies such as autonomous driving, AR/VR, and advanced driving assistance systems. For example, more accurate shape detection in AR/VR devices and smartphones depends on the improved range resolution of medium and short range LiDAR. This requires a single photon detector with improved timing jitter performance.LiDAR calculates the distance an...
Researchers printed microscale lenses directly onto optical fibers, allowing them to tightly combine the fibers and laser crystals into a single laser oscillator.Scientists have used 3D printing polymers in new micro optical technology, which can reduce the size of lasers and be used in various new applications, including the laser radar system for autonomous vehicle technology and cancer treatmen...
