主　　题：DPSK amplifier penalty 

摘      要：We experimentally demonstrate that,based on operational condition optimization,a common quantum well (QW) semiconductor optical amplifier (SOA) has the ability of amplitude regeneration for return-to-zero (RZ) differential phase shift keying (DPSK) *** a single-channel RZ-DPSK regeneration scheme,a significant eye-opening enhancement and a negative power penalty of about 1.0 dB are *** dual-channel RZ-DPSK regeneration,it can also be found that the eye-opening improvement and power penalty decrease in each *** addition,the DPSK regeneration scheme based on a single QW SOA is quite simple and stable.
