英文摘要	Brillouin frequency shift and Brillouin gain spectrum of different modes in few mode fiber were calculated by full vector finite element method. In addition, the influences of pump power, effective transmission length and pulse width on the slow-light time delay and pulse broadening factor of different modes in few mode fiber were also simulated. The simulation results show that characteristics of tunable slow light of different modes in the FMF are different, the larger time delay and pulse broadening factor of different modes are achieved as pump power and effective transmission length increasing, the time delay and pulse broadening factor of intramodal stimulated Brillouin scattering are greater than intermodal stimulated Brillouin scattering for a given input pump power. By critical tuning parameters, the time delay of LP01-LP01, LP11-LP11 and LP01-LP11 mode pairs are respectively 643.7 ns, 362.6 ns and 213.2 ns at a given input pump power of 0. 5 W and the effective fiber length of 1 km, pulse broadening factors are 1.346, 1.207 and 1.126, separately. © 2019, Science Press.
