摘　　要：低成本、低功耗和可集成是目前波长变换技术所追求的目标。提出一种基于法布里-珀罗型激光二极管(FP-LD)中模式竞争机理的全光波长变换方案。通过在FP-LD不同模式中注入恒值探测光和信号光产生双模式竞争,从而实现波长变换。对波长变换产生的原理进行了分析,并对波长变换后信号的信噪比、消光比以及啁啾特性进行了实验研究。进行了10Gb/s非归零(NRZ)信号在不同波长上的波长变换及其20km传输实验。误码率测试数据结果表明波长变换后的功率代价小于1dB,各个波长信号传输20km后的功率代价均小于1dB。The goal of wavelength conversion technology is low cost,low-power dissipation and integratability.An all-optical wavelength conversion scheme based on Fabry-P？？rot laser diode（FP-LD） mode competition is proposed.The wavelength conversion employing dual-mode competition of the FP-LD is realized by injecting probe light and signal light into different modes of the FP-LD.The principle of wavelength conversion is analyzed.The signal-to-noise ratio（SNR）,extinction ration（ER） and chirp characteristics of the signal after wavelength conversion are studied experimentally.The wavelength conversion and transmission experiments of 10 Gb/s non-return-to zero（NRZ） signals at different wavelengths are conducted.The results of bit error rate test show that the power penalty after wavelength conversion is less than 1 dB,and the power penalties of different wavelengths after 20 km transmission are all less than 1 dB.
