We have derived an explicit analytical expression for the gain of a Brillouin fiber amplifier operating in the depleted pump regime. The accuracy of the obtained formula is validated both numerically and experimentally.
We demonstrate engineered refractive index profiles for the mitigation of nonlinear optical impairments such as stimulated Raman scattering and stimulated Brillouin scattering. These fibers offer performance improvements over conventionally used large mode area fibers.
We experimentally demonstrate a stimulated Brillouin scattering free, all fiber phase conjugator using 1-m length of our fabricated bismuth oxide-based nonlinear fiber. Using the conjugator, error-free, dispersion compensated transmission of a 10-Gbit/s NRZ signal over a 150 km SMF transmission link is readily achieved.
Scattering of a dispersive wave on a soliton in a cobweb PCF resulting in generation of new spectral components is observed directly with XFROG technique. Recent analytical theory and numerical modeling confirm the results.
We report a bandwidth-enhanced multi-wavelength source from a stimulated Brillouin scattering assisted erbium-doped fiber laser using four-wave-mixing in a 35-cm highly nonlinear bismuth oxide fiber. Tuning of output wavelengths and wavelength spacing have been demonstrated.
We describe a beam cleanup setup to convert a multimode beam into a singlemode beam by stimulated-Brillouin-scattering in a multimode gradient-index fiber. A M2=6.5 beam is converted into a M2=1.3 beam with 31% efficiency.
We propose the use the recently discovered effect of spectral self-phase conjugation in SBS for coherent beam combining of the output from an array of high power fiber amplifiers.
We report a novel method to enhance the performance of Brillouin optical correlation domain analysis system based on intensity modulation of light source. Distributed measurement over 1-km range is successfully demonstrated with 30-cm spatial resolution.
