Observation of phase conservation in multiwavelength binary phase shift–keying pulse-sequence generation at 10 Gbits/s by use of a spectrum-sliced supercontinuum in an optical fiber

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(-10) is successfully generated over a 20-nm-wide wavelength range 1540-1560 nm.
