There are different signal formats in optical fiber communication networks. In such networks, processing function in network node should work independently from the signal formats, such as intensity- and phase-modulations.
In this project, regenerative optical signal processing functions, such as pulsewidth tunable regenerative pulsewidth conversion, optical multicasting function to distribute a single-channel signal to multiple-wavelength channels, conversion of a wavelength-division multiplexing signal to a optical time-division multiplexing signal, and distortion-compensating variable optical delay line to change the timing of the signal, are studied. These processing functions are investigated for phase-modulated signal as well as conventional intensity-modulated signals. The results of the study suggest that most of these functions are applicable independent from the signal formats.
