| Research Abstract |
Variable optical delay-line is very important for optical signal timing adjustment in optical communication networks. In this study, optical Fourier transformation(OFT) is appliedto such variable optical delay-line to realize distortion-free operation. The characteristics of the OFTincorporatedoptical delay-line, which is realized with a phase modulator, a suitable length of opticalfiber, and a wavelength converter is evaluated. Distortion-free as well as variable time-delay operation of the delay-line is successfully demonstrated.
