Optical fiber communication is a key technology that supports the massive growth of Internet traffic. During the last three decades, transmission capacity per fiber has been increased five orders of magnitude. Our laboratory has been established on April 2017, and we are working on optical fiber communication system technologies and its applications. Our research target covers various aspects of optical communication systems such as long-haul optical transport networks, optical access networks and data-center networks. The transmission performance of long-haul transport networks has dramatically increased by digital coherent transmission scheme. However the attainable per-fiber capacity is fundamentally limited by fiber nonlinearity, and thus one of main topics in our laboratory is nonlinear compensation techniques to overcome this limitation. We are also focusing on advanced modulation-detection schemes to realize high-speed and low-cost interfaces, and working on optical performance monitoring technique that is indispensable for providing highly-reliable communication services.
