【Abstract】 All-Optical 2R( Reshaping and Re-amplifying) Regeneration is a key optical signal processing technology in optical communication. All-optical 2R regeneration scheme utilizing the nonlinearity of cross gain compression( XGC) in conjunction with transient-cross phase modulation( T-XPM) in semiconductor optical amplifier( SOA) is proposed. All-optical 2R regeneration for 25-Gb / s to 100-Gb / s degraded return-to-zero( RZ) OOK signals are demonstrated experimentally. It shows that the quality of the signals degraded by noise of amplified spontaneous emission( ASE) is improved and the error floor of the degraded signal is eliminated by using the proposed 2R regeneration scheme. Besides,this 2R regeneration features photon-integratable,wavelength-preserving and being suitable for non-return-zero( NRZ)all-optical signal regeneration更多还原
