| Outline of Final Research Achievements |
In this study, investigations on digital simultaneous detection of optically Fourier-encoded synchronous optical code division multiplexing (FE-SOCDM) were performed. The results are as follows: (1) Experimental demonstration of digital simultaneous detection of FE-SOCDM signals. (2) Clarification of simultaneous reduction of timing-jitter and frequency chirp on gain-switched optical short pulse source. (3) Numerical demonstration of digital impairment compensation scheme for FE-SOCDM signals. (4) Phase error reduction of FBG-based Fourier encoders based on structure identification of FBG encoders by using down-hill-simplex (DHS) algorigthm and boost yield in fabrication of FBG-based Fourier encoders.
