| Outline of Final Research Achievements |
In optical communication networks, optical node functions are very important which convert the signal wavelength and waveform and/or compensate signal distortions. So far, such optical node functions have assumed the same signal format. On the other hand, there are many signal formats according to the properties of the signal sources and destinations. In this study, optical node functions which allow multiple signal formats were investigated.
The research results include realization of (1) wavelength/waveform conversion and waveform reshaping function applicable to various signal modulation formats, (2) polarization- and signal format-independent waveform conversion function, and (3) OTDM(optical time-division multiplexing) to WDM(wavelength-division multiplexing) conversion function.
