“…For the SMF transmission using the 80 kHz linewidth laser, the output power was severely limited by the SBS, and it was observed that the output power did not change as the input power increased when the power exceeded 120 mW. In SMF-28, the values of A eff and g B are shown as approximately 80 µm 2 and 1.3 × 10 −11 m −1 W −1 , respectively [17]. Substituting these values into Eq.…”

Hollow-core photonic bandgap fibers exhibit nonlinear properties. In comparison with conventional silica-core optical fibers, we experimentally evaluate whether the hollow-core photonic bandgap fiber has extremely low nonlinearity compared with silica-core optical fibers in terms of stimulated Brillouin scattering and four-wave mixing. A low nonlinearity is useful for high-power optical transmission applications.

“…1 Among these nonlinear effects, the nonlinear inelastic scattering effects have attracted the most notable interest. [3][4][5][6] SBS as well as other nonlinear effects are very weak and require huge amounts of power and long fiber lengths. This process can be electrostrictively amplified and gives rise to stimulated Brillouin scattering (SBS).…”

Stimulated Brillouin scattering (SBS) performances of small core tellurite photonic crystal fibers (PCF) are rigorously studied. We propose a design of tellurite PCF that is used for slow-light-based applications. We developed a two-dimensional finite element mode solver to numerically study the acoustic and optical properties of complex refractive index profiles including tellurite PCF. Our results include the calculation of Brillouin gain spectrum, Brillouin gain coefficient (g B ) and Brillouin frequency shift by taking into account the contribution of the higher-order acoustic modes. Several simulations were run by varying the air-filling ratio of various PCF structures to enhance the SBS. The real scanning electron microscope image of a small core of highly nonlinear tellurite fiber is considered. Optimized results show a frequency shift of 8.43 GHz and a Brillouin gain of 9.48 × 10 −11 m∕W with a time delay between 21 and 140 ns. Such fibers have drawn much interest because of their capacity for increasing and tailoring the SBS gain.

“…This is mainly attributed to its numerous and unique advantages, such as its ability to create resonance at any wavelength by simply changing the pump wavelength, its operations at room temperature, and its excellent compatibility with the communication system available. To date, the SBS-based slow light in various fibers, including standard single-mode fibers, bismuth-oxide fibers [17], chalcogenide fibers [18,19], tellurite glass fibers [20,21], and photonic crystal fibers [22,23] has been investigated.…”

With the idea of controlling the polarizations of the pump and Stokes beams in an optical fiber, a simple scheme is presented for enhancing the stability of the stimulated Brillouin scattering (SBS) interaction and thus that of the SBS-based slow light. For this purpose, a special slow-light element is constructed by fusing a polarization-maintaining circulator (its fast axis being blocked) to each terminal of the polarization-maintaining fiber (PMF). This configuration ensures that the pump and Stokes beams always have identical polarization in the whole fiber during the SBS interaction. An experimental setup is established accordingly. The SBS gain feature and the slow-light performance are studied. A tunable time delay with a slope of 0.82 ns dB−1 is demonstrated for a Gaussian pulse with a width of 88.9 ns. The experimental results with and without polarization management are compared. It is found that such a polarization-managed scheme can improve both the stability of the Brillouin gain and that of the time delay of the Stokes pulse. Moreover, for the same pump power, the Brillouin gain is also enhanced.
