光纤中三角斯托克斯脉冲的受激布里渊散射慢光（英文）

SBS Slow Light of Triangular Wave Stokes Pulses in Optical Fibers

采用龙格库塔法和特征线法对光纤中受激布里渊散射耦合方程组进行数值求解,研究斯托克斯脉冲的增益、能量和半高全宽对时延和脉冲展宽的影响.结果表明:三角脉冲的增益、能量和宽度对时延和脉冲展宽都有影响,最大时延随着脉冲能量的减小而增加.脉冲宽度越窄,时延会越大.优化三角斯托克斯脉冲的增益、能量和宽度,可以获得最大时延和小的脉冲形变.该研究可为光通信和传感器件设计提供参考.

The coupled amplitude equations of stimulated Brillouin scattering in optical fibers are numerically solved with fourth-order Runge-Kutta formula and characteristics methods,the influences of gain,energy,and Full Width at Half Maximum（FWHM）of injected triangular wave Stocks pulses on time delay and pulse broadening are investigated.The results show that the time delay and pulse broadening depend on the gain,energy and FWHM of the triangular pulses.The maximum time delay increases with the injected pulses energy decreasing.Smaller FWHM of pulse induces larger relative time delay.The maximum time delay and less pulse broadening can be obtained by optimizing the gain,energy,and FWHM of injected triangular wave Stocks pulses.These results provide reference for designing novel optical communication or sensing components.
