"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.

Advancements in On-Chip Photonic Technology for High-Speed and Low-Power Applications.

Researchers in Germany and the Netherlands have developed a complete entangled photon source on a chip that is about the size of a one euro coin. The team used a new architecture to combine several integrated photonic technologies into one device, creating a photonics system-on-a-chip that generates entangled photons. The chip creates pairs of frequency-entangled photons with 99% fidelity about 1000 times per second. The team is now working towards extending the on-chip photonic capabilities to include the creation of multiphoton cluster states.
