| Abstract: | All-optical clock recovery is the key technology in 3R all-optical regeneration.In this paper,to reduce the pattern effect in bit clock recovery using injection mode-locked laser based on semiconductor optical amplifier(SOA),we propose a novel technology named nonlinear polarization rotation,which is proved to be very effective by numerical calculation. |

| Keywords: | Clock recovery Pattern effect Nonlinear polarization rotation |
