Simple technique to achieve fast light in gain regime using Brillouin scattering.
We describe a novel technique based on stimulated Brillouin scattering for propagating fast light (signal advancement) with low distortion in optical fibers. The essence of the technique relies on the presence of two separate gain resonances in the Brillouin gain spectrum generated by cascading two different fiber segments showing distinct Brillouin shifts. It can be shown that in between these...
متن کاملShear Brillouin light scattering microscope.
Brillouin spectroscopy has been used to characterize shear acoustic phonons in materials. However, conventional instruments had slow acquisition times over 10 min per 1 mW of input optical power, and they required two objective lenses to form a 90° scattering geometry necessary for polarization coupling by shear phonons. Here, we demonstrate a confocal Brillouin microscope capable of detecting ...
متن کاملLow distortion fast light in an optical fiber using stimulated Brillouin scattering
We demonstrate experimentally a novel approach for fast light generation based on a wideband compound spectral resonance using stimulated Brillouin scattering. The pulses experience fast light with extremely reduced distortion and small amplitude change. ©2007 Optical Society of America OCIS codes: (060.4370) Nonlinear optics, fibers; (290.5900) Scattering, stimulated Brillouin; (350.5500) Prop...
متن کاملThermal Effects Study on Stimulated Brillouin Light Scattering in Photonic Crystal Fiber
we investigate the temperature-dependences of the Brillouin frequency shift in three different kind of single-mode fibers using a heterodyne method for sensing temperature. Positive dependences coefficients of 0.77, 0.56 and 1.45MHz/0C are demonstrated for 25 km long single-mode fiber, 10 km long non-zero dispersion shifted fiber and 100 m photonic crystal fiber, respectively. The results indic...
متن کاملHigh-fidelity, broadband stimulated-Brillouin-scattering-based slow light using fast noise modulation.
We demonstrate a 5-GHz-broadband tunable slow-light device based on stimulated Brillouin scattering in a standard highly-nonlinear optical fiber pumped by a noise-current-modulated laser beam. The noisemodulation waveform uses an optimized pseudo-random distribution of the laser drive voltage to obtain an optimal flat-topped gain profile, which minimizes the pulse distortion and maximizes pulse...
