Lithium niobate nanophotonics

Lithium niobate (LiNbO₃) crystal exhibits exceptional electro-optic, acoustic-optic, and nonlinear-optic properties, establishing itself as a highly promising material platform for diverse applications in optical communication networks, microwave photonic systems, and quantum information processing. Our research focuses on the design and nanofabrication of essential lithium niobate components, including waveguides, microdisks, and linear/nonlinear photonic crystals. These components find applications in laser frequency conversion, quantum light generation, electro/acousto-optic modulators, and the development of surface acoustic wave (SAW) devices.
