| Research Abstract |
We studied optical signal reshaping and noise reduction methods with an aim to realize long-distance and high-speed optical fiber transmission systems with superior tolerance to various kinds of waveform distortion and noise. Following results are obtained: (1) we proposed opto-electronic hybrid signal regeneration schemes where signal reshaping is partially performed in the electrical domain and demonstrated their effectiveness by experiments and numerical simulation, (2) we showed that electrical signal processing such as sequence estimation at the receiver can enhance dispersion tolerance of the system periodically equipped with signal regenerators to some degree, and (3) we proposed and discussed high functionality all-optical signal regeneration such as phase-sensitive amplification for QPSK signals.
