Polarization Properties of Stimulated Brillouin Scattering and their Implications on Slow and Fast Light
Vector formalism for stimulated Brillouin scattering amplification in birefringent fibers is used to model the fiber as an equivalent, pseudo-linear, polarization-dependent gain medium. Implications on slow and fast light setups are discussed. ©2009 Optical Society of America OCIS codes: (290.5900) Scattering, stimulated Brillouin; (120.5410) Polarimetry; (060.2300) Fiber measurements.
متن کاملPolarization attributes of stimulated Brillouin scattering slow light in fiber
The polarization-related properties of stimulated Brillouin scattering (SBS) processes in long, randomly birefringent, standard optical fibers are examined. Evolution equations for the pump and signal waves, in the presence of both birefringence and SBS, are provided in Jones and Stokes spaces. It is shown that in the undepleted pump regime, the amplification of the SBS signal wave is equivalen...
متن کاملPolarization-induced distortion in stimulated Brillouin scattering slow-light systems.
The vector analysis of stimulated Brillouin scattering amplification in birefringent fibers is extended to include signal pulses. The analysis finds that the different slow-light delays experienced by the states of polarization corresponding to maximum and minimum gain may result in severe pulse distortion. Thus, a generally polarized pulse, experiencing only a moderate gain, can become broader...
متن کاملNoise properties of propagation through slow- and fast-light media
We consider the fundamental noise properties of propagation through slowand fast-light optical media based on gain or loss processes. For purely quantum mechanical reasons, any gain or loss process will add noise to a transmitted light field. We derive a relation between the noise figure describing the decreased signal-to-noise ratio of the transmitted laser pulse and the fractional delay or ad...
متن کاملPolarization properties of subwavelength metallic gratings in visible light band
Optical polarization properties of aluminum, gold and aluminum/gold subwavelength metallic gratings (SWMGs) are investigated numerically in the visible light band. Their performance as polarizing beam splitters are simulated with RCWA for varied metallic materials, grating depth and incident angle. Metallic waveguide theory is applied to explain the performance difference between Au and Al grat...
