Optical communications, which support global Internet traffic, have significantly improved in performance over the past three decades and will continue to demand higher speeds and larger capacity. This is due to the anticipated increase in data traffic driven by developments such as 4K/8K ultra-high-definition broadcasting, immersive metaverse environment, autonomous mobility, and large-scale AI computing.
To construct future exabit/s-class and energy-efficient optical communication systems, breakthroughs are needed to overcome current technical limitations. We are developing, both theoretically and experimentally, high-functional optical signal processing technologies employing advanced quasi-phase-matched nonlinear optical devices. These functional devices can process ultra-fast and ultra-wideband data signals all-optically with minimal latency and power consumption.
Our research includes both theoretical modeling and experimental demonstrations, and we have achieved high performance in the system experiments. Through joint research with domestic companies and overseas universities, we also aim to realize a new generation of smart optical communication systems suitable for practical use.
