-chalcogenide photonic crystal fiber is reported for generation of a tunable slow light. Maximum allowable pump power for undistorted output pulse, Brillouin gain, and time-delay experienced by the pulse propagating in designed photonic crystal fibers are simulated. We have found that Brillouin gain upto ~88 dB/m and time delay up to ~137 ns can be obtained from 1-m-long photonic crystal fiber pumped with 100 mW. Simulated results indicate that the time delay experienced by the pulse can be tuned with the pump power and structural parameters of As
