| Outline of Final Research Achievements |
In order to enhance the capacity of optical fiber communications, this research project explores the technologies for optical single sideband (SSB) modulation, which requires Hilbert transformations for phase-shift method. This research includes the following three studies; (1) A study on inverse Hilbert transformation for optical SSB receivers and all-optical sideband recovery method, (2) A study on improve method about peak-to-average power ratio of optical SSB modulation, (3) A study on the influence of wavelength saving scheme on network node scale in in optical waveband switching networks.
