interview: Hirotaka Ono

In an interview, Hirotaka Ono of NTT Photonics Laboratories talked about his field of research. Ono said that he have been engaged in the research and development of optical fibre communication technologies for both long-haul and metro networks. The technologies include optical fibre amplifiers, highly nonlinear fibre devices, photonic crystal fibres, and tuneable optical dispersion compensators. Since 2011, he have mainly been working on the research of lumped and distributed optical amplification technologies needed for constructing long-haul space-division-multiplexing transport systems. Recent progress on communication technologies and services has led to rapid growth of Internet traffic, and the demand for high capacity optical transport networks is expected to continue over the coming years.
