SBS based slow-light generation in rectangular lattice graded-index photonic crystal fiber: Design and analysis

Theoretical analysis of stimulated Brillouin scattering based slow-light in As2Se3 based chalcogenide photonic crystal fiber has been reported. A maximum time-delay of 252.8 ns has been achieved for 1 m long fiber at input pump power of 9.8 mW. A maximum gain of 99 dB/m has been obtained for the same input pump-power. The simulated results indicate that the time-delay can be tuned by varying the input pump-power and the size of the air holes to obtain tunable features. We feel that the comprehensive theoretical investigation carried out in this paper have potential impact in the design and development of slow-light based photonic devices.
