8 /spl times/ 40 Gb/s RZ all-optical broadcasting utilizing an electroabsorption modulator

摘要

We experimentally demonstrate all-optical broadcasting through simultaneous 8 /spl times/ 40 Gb/s wavelength conversion in the RZ format based on cross absorption modulation in an electroabsorption modulator. The original intensity-modulated information is successfully duplicated onto eight wavelengths that comply with the ITU-T proposal. The advantages of the proposed wavelength conversion scheme are discussed.
