Outline

Our team is advancing innovative research in terahertz (THz)-wave nonlinear photonics. We have achieved world-leading results, including kilowatt-level THz-wave generation, attojoule-level THz-wave detection, and backward THz-wave parametric oscillation. Moving forward, we aim to develop Terahertz-System on a Chip (T-SoC) technology. We are focusing on next-generation sensing technologies such as coherent detection and quantum interference with non-classical light to drive future innovations. By strengthening collaborations with universities and industries worldwide, we are expanding our international network and fostering young researchers, with a goal to promote THz-wave technologies and technological advancements globally.
