"Revolutionizing Laser Technology: Lithium Niobate Integrated Photonics for Rapid Adjustability"

Researchers have developed a hybrid wafer stack combining lithium niobate (LiNbO3) and silicon nitride (Si3N4) that allows for fast frequency tuning and modulation stability in lasers. The hybrid chip utilizes microresonator structures to achieve laser self-injection locking and voltage-controlled frequency tuning. The study demonstrates the successful application of the hybrid circuit in LiDAR technology and highlights the potential of thin-film LiNbO3 structures in photonics.
