EPFL_and_IBM_Develop_Hybrid_Integrated_Laser_with_Low-Frequency_Noise_and_Fast_Wavelength_Tuning(720p)

Researchers from EPFL and IBM have created a hybrid integrated tunable laser by combining lithium niobate with silicon nitride. This new laser has low-frequency noise and fast wavelength tuning, making it ideal for light detection and ranging (LiDAR) applications. The team demonstrated its ability to measure distances with high precision, which could revolutionize optical ranging technology. The laser's capabilities also have the potential to lead to the development of integrated transceivers for telecommunications and microwave-optical transducers for quantum computing
