Abstract :
We demonstrate high extinction-ratio orthogonal label switching of DRZ/DPSK generated by a dispersion-flattened photonic-crystal-fiber (PCF). Label removal and re-insertion are demonstrated with improved receiver-margin compared to conventional NRZ/DPSK because of the higher extinction-ratio.
