• An InGaAsP/InP semiconductor coupled-waveguide structure was investigated experimentally and theoretically as a potential dispersion compensator. In-depth numerical analysis of the waveguide-length dependence of autocorrelation-signal widths(which are related to pulse durations)well explains that obtained experimentally. This strongly indicates that the observed pulse-compression is attributed to dispersion compensation by using significantly enhanced group-velocity-dispersion of supermodes in the coupled-waveguide structure. Furthermore, a numerical and experimental study revealed that a pedestal observed in the narrowest signal is not an intrinsic problem but most likely comes from the difference in waveguide parameters of a fabricated coupled waveguide and a designed coupled waveguide.
