چکیده انگلیسی
We experimentally study both reshaping of nonreturn-to-zero (NRZ) signal and NRZ to pseudoreturn-to-zero (PRZ) format conversion based on self-phase modulation of a semiconductor optical amplifier (SOA) and detuning an optical bandpass filter (OBF). When an OBF with 1Â nm bandwidth is blue shifted by 0.8Â nm, the distortion of the amplified NRZ signal at 10Â Gbit/s is shown to be eliminated completely. When an OBF with 0.32Â nm bandwidth is red shifted by 0.42Â nm from the carrier frequency, NRZ-to-PRZ conversion at 10Â Gbit/s is obtained. A holding beam is used to suppress the SOA noise and improve the output extinction ratio (ER). The output ER of both the reshaped NRZ and the converted PRZ is larger than 10Â dB when the signal wavelength is longer than 1540Â nm, and an input power dynamic range from â7Â dBm to 2Â dBm is obtained at a signal wavelength of 1563.6Â nm. The average power of the reshaped NRZ signal is about 3Â dBm at an input power dynamic range of 13Â dB. The amplitude fluctuation of the converted PRZ signal is around 1.6Â dB.
