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.

10 Gb/s OCDM/WDM multiple access using spectrum-sliced supercondinuum BPSK pulse code sequences

We experimentally demonstrated 10 Gb/s OCDM/WDM multiple access, in which spectrum-sliced supercontinuum BPSK pulse code sequences are used as multi-wavelength optical code sources.
