英文摘要	Slow light of stimulated Brillouin scattering in double-clad As2Se3 chalcogenide photonic crystal fibers was investigated theoretically. The influence of air hole size of the inner and outer cladding of the PCFs on Brillouin gain spectrum, Brillouin threshold time delay, and Brillouin gain by taking into account the contribution of the high-order acoustic mode was numerical simulated by full vectorial finite element method. The simulated results indicate that the properties of slow light are affected more obviously by varying the air filling fraction in the inner cladding and less affected by the air hole size of the outer cladding. We found that with the time delay up to 705ns, Brillouin gain up to 40dB can be achieved with pump power of only 10mW in a 1m long chalcogenide PCF when the air filling fraction in the inner cladding is 0.9. The pertinent results can be of great importance for studying and designing the optical devices or optical sensors based on this kind of PCF. © 2020 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
