Phase conservation in multiwavelength binary phase shift–keying (BPSK) pulse-sequence generation by slicing of a supercontinuum spectrum with a dispersion-flattened normal-dispersion fiber is experimentally observed. A 10-Gbit/s BPSK pulse sequence with a bit-error rate of <10<sup>-10</sup> is successfully generated over a 20-nm-wide wavelength range 1540–1560 nm.
