Revolutionizing Electronics: Laser Technology Controls Electron Emission at Unprecedented Speeds.

Scientists at EPFL and IBM have developed a hybrid integrated tunable laser by combining lithium niobate and silicon nitride, which offers low frequency noise and fast wavelength tuning. This laser has potential applications in LiDAR, telecommunications, and quantum computing due to its unique combination of properties. The hybrid platform has the potential to realize integrated transceivers for telecommunications as well as microwave-optical transducers for use in quantum computing.
