About us

The Optical Access Technology Laboratory conducts integrated research and development on optical information and communication technologies ranging from device level to system level.
 Our objective is to propose innovative communications systems which meet the stringent network requirements in the Beyond 5G era from device level and demonstrate their practicality and effectiveness through system-level experiments.
Our research interests include high-performance optical integration, microwave/millimeter-wave photonics, and optoelectronic signal processing.
 We are always striving to develop innovative technologies in collaboration with industry and academia.

Projects

R&D on Ultra-High-Speed, 3-D Integrated ICT Device Technologies

massive_concept
 With the goal of minimizing energy and resource footprints while maintaining low-latency, high-capacity pipelines, we pioneer ultra-high-speed, 3-D integrated ICT hardware through the co-design of optical and RF devices. Crucial to driving this technological frontier, our work simultaneously pushes the boundaries of high-frequency, high-precision metrology. 
 

R&D on All-Band Seamless Access Technologies

 This research establishes All-Band Seamless Access Technologies to achieve flexible, resilient, end-to-end data transmission across diverse edge networks, fully bridging core infrastructures with data center environments, residential/commercial buildings, and mobile platforms. By co-designing photonic, wireless, and processing domains while simultaneously advancing the limits of high-frequency, high-precision metrology, we empower the long-term scalability and sustainable development of intricate edge network ecosystems.
