“…But with the more powerful pump, the signal pulse seems to be more noisy and distorted. This is due to more spontaneous Brillouin scattering mixed in the amplified signal under the condition of high pump power [2]. And in this experiment noise is not filtered off from amplified signal, and the noise can be efficiently suppressed with the narrow bandwidth filter.…”

“…The concept of slow light was presented in the background. After more than ten years of development, it has been widely used in the areas such as optical delay line, all-optical buffering, and optical communication [1]- [3]. There are many methods of generating slow light, more typical methods include electromagnetically induced transparency, coherent population oscillation, and stimulated Brillouin scattering.…”

Magnetic nanoparticles in magnetic fluid film can be agglomerated to form a new type of magnetic fluid photonic crystal when magnetic field is applied perpendicular to the surface of the film. The lattice constant of the magnetic fluid photonic crystal can be tuned by changing the intensity of the applied magnetic field. In this paper, photonic bandgap of the magnetic fluid photonic crystal was analyzed theoretically, and it exhibited better magnetic tunability when the sweep rate of applied magnetic field was 2 Oe/s. Then, a magnetic fluid photonic crystal waveguide was presented, and slow light was generated. The effect of the applied magnetic field on slow light was studied based on experimental data. The results showed that group velocity below 0.35c could be obtained, and the shift of working wavelength with magnetic field intensity was the most obvious when the sweep rate of applied magnetic field was 10 Oe/s. Compared with traditional photonic crystals, the magnetic fluid photonic crystal exhibited the advantage of better magnetic tunability and easier formation, it would be potentially applied to the fabrication of new optoelectronic device.

“…Stimulated Brillouin scattering (SBS) [2,3] slow light is particularly attractive for communications since the approach can be adopted in an optical fiber and can operate at an arbitrary wavelength. A limitation of SBS is its narrow gain bandwidth in the order of tens of MHz.…”
