Abstract

In this paper, we have calculated the highly efficient generation of the slow light based on the Stimulated Brillouin scattering (SBS) in a small core As₂Se₃ chalcogenide PCF. A Brillouin gain coefficient, g_B. of 9.05 10-9 m.W-1 is found around the acoustic frequency of 8.08 GHz in small core diameter of 1.69 μm with 1.5 μm² effective mode area at 1550 nm. A Brillouin gain of 77.3 dB was achieved with only 10 mW pump power in a 10-m fiber length, which leads to the optical time delay of 94 ns. In terms of the proposed figure of merit, it shows 2.77 dB/mW/m which is about 110 times more efficient than conventional single-mode fibers. These fibers are expected to have potential applications in realization of compact slow light devices.
