增益调制型波长转换器消光比均衡的研究

Study on Extinction Ratio Equalization of Up/Down Wavelength Conversion Based on Cross gain Modulation in Semiconductor Optical Amplifier

利用半导体光放大器 (SOA)中交叉增益调制 (XGM)效应成功地实现了 62 2 Mb/ s和 2 .5Gb/ s信号的波长转换。对波长上 /下转换性能的研究表明 ,使用增益峰值波长比信号波长长的SOA可以有效地实现上 /下转换效率和消光比均衡 ,从而使这种类型的波长转换器在波分复用器(WDM)

The wavelength conversion of 622 Mb/s and 2.5 Gb/s channels based on XGM in SOA has been successfully realized. The study on performance of up/down conversion shows that extinction ratio of up/down conversion can be effectively equalized when a SOA with gain peak wavelength longer than signal wavelength is used. So the wavelength converters based on XGM will have more applications in WDM all optical network.
