Optical signal processing is among the fundamental and significant functions for optical transmission, optical switching and optical access. The related study is vital and the involved problems are prospective. With the development of advanced optical modulation and bandwidth allocation, the parallel processing of multi-dimensional optical signals has become one of the key technologies in physical layer to improve the flexibility, scalability and spectral efficiency of optical communication systems and networks. With solid background of optical signal processing, the project team will conduct theoretical and experimental study on key scientific issues of the parallel processing of multi-dimensional optical signals. The interaction among multi-channels in nonlinear media is to be modeled, as well as the evolution of phase noise. Novel schemes regarding parallel processing of multi-dimensional optical signals are to be proposed and validated, including the phase noise suppression, the parallel logical operation, the modulation format conversion and the optical performance monitoring. The project team expects to make substantial progress in the aforementioned basic research and thus provide useful results for resolving some theoretical and application-related problems in optical communications.
