摘　　要：基于半导体光纤环形腔激光器的四波混频型可调谐全光波长转换器的宽带理论模型,从理论上研究了输入信号光功率、注入电流、两个耦合器的耦合比、激射光波长和半导体光放大器有源区长度对转换光频率啁啾的影响.结果表明:转换光的频率啁啾随着输入信号光峰值功率、注入电流以及SOA有源区长度的增大而增大,随两个耦合器耦合比的增大而减小.Using the broad-band dynamic model of a tunable wavelength converter based on four-wave mixing （FWM） in a semiconductor fiber ring laser （SFRL）, factors which affect converted signal chirp, such as the input signal power, injection current, the coupling of two couplers, the lasing wavelength and the length of SOA, are investigated. The numerical results show that the converted signal chirps increase with the input signal power, injection current and the length of SOA increasing, the converted signal chirps are decreased as the coupling coefficient of the two couplers increase.
