Integrated Photonic Circuits on Lithium Niobate and Silicon Platforms
This research community designs and fabricates integrated photonic circuits for optical communication, quantum information processing, and photonic computing, utilizing thin-film lithium niobate and silicon-based waveguide technologies.
The work centers on the development of high-performance waveguides, modulators, and frequency combs using thin-film lithium niobate, silicon, and silicon nitride substrates. Recurring applications include optical frequency combs for precision measurement, quantum key distribution systems, and photonic neural networks for machine learning. The community also focuses on nonlinear optical effects such as harmonic generation and optical parametric oscillation, enabling the creation of tunable light sources and compact signal processing engines. These components are integrated into photonic integrated circuits to replace electronic components in high-speed data transmission and sensing applications.
