| Abstract | |
Photonic Integrated Circuits (PICs) provide an efficient and scalable platform for processing and transmitting information. Such circuits rely on the manipulation of electromagnetic waves, often achieved via interaction with materials exhibiting specific properties. Lithium Niobate (LN) is particularly well-suited for this task. Its large nonlinear and electro-optical coefficients enable frequency-mixing and high-speed modulation processes, advancing applications in communications and sensing, and making it a promising candidate for photonics-based quantum information technology. Thin-Film Lithium Niobate (TFLN) in particular allows for tight confinement of the interacting fields and unlocks additional degrees of freedom for device design. Substantial progress has been made over the past decade, demonstrating ultra-low optical losses and the generation of key nonclassical states of light such as single-photon, entangled, and squeezed states. In this work, we develop a microfabrication recipe for photonic devices in thin-film lithium niobate suitable for local cleanroom infrastructure. Periodic poling of TFLN for quasi-phase-matching is successfully implemented, and a low-loss edge coupling setup is demonstrated and tested (AU) | |
