Photonic generation of microwave arbitrary waveforms using stimulated Brillouin scattering and Sagna
[期刊论文] 作者：LI Xiang,DU Cong,LIU Fangming,ZHANG Zhenguo,DONG Wei,
来源：光电子快报（英文版） 年份：2021
A photonic approach is proposed to generate microwave arbitrary waveforms based on the stimulated Brillouin scattering(SBS)effect and the Sagnac loop.The Sagnac loop is utilized to generate the optical signals of±1st-order and±3rd-order s......
