建立了单信道40 Gbit/s归零-差分相移键控码(RZ-DPSK)传输系统模型,详细地分析并比较了线性相位噪声和非线性相位噪声对系统性能的影响.结果表明,由放大器自发辐射(ASE)噪声带来的线性相位噪声对传输系统的性能影响最大,ASE与自相位调制(SPM)相互作用引起的Gordon-Mollenauer(G-M)相移次之,带内四波混频(IFWM)的...
DPSK是数字调制方式的一种。 差分移相键控（DPSK）：利用调制信号前后码元之间载波相对相位的变化来传递信息。
摘要: RZ-DPSK to NRZ-DPSK format conversion in a silicon microring resonator is demonstrated experimentally for the first time at 41.6 Gb/s. The converted signal eye diagrams and bit-error-rate measurements show the good performance of the scheme....
