On-chip stimulated Brillouin scattering

Optics Express, 2011
We demonstrate on-chip stimulated Brillouin scattering (SBS) in an As2S3 chalcogenide rib waveguide. SBS was characterized in a cm long waveguide with a cross-section 4 μm x 850 nm using the backscattered signal and pump-probe technique. The measured Brillouin shift and its full-width at half-maximum (FWHM) linewidth were ~7.7 GHz and 34 MHz ...

Opto-mechanical time-domain analysis based on coherent forward stimulated Brillouin scattering probing

, 2020
Guided acoustic wave Brillouin scattering has gained considerable interest in recent years because of its capacity to detect mechanical features of materials surrounding the optical fiber.

Analogue of electromagnetically induced absorption in the microwave domain using stimulated Brillouin scattering

Communications Physics, 2020
Electromagnetically induced transparency/absorption (EIT/EIA) tailor the amplitude and phase response of an absorption resonance to create large dispersion, which has been exploited for applications in slow- and fast-light, and quantum information ...

Lowering backward Raman and Brillouin scattering in waveguide Raman wavelength converters

Journal of the European Optical Society-Rapid Publications, 2017
Background Liquid filled hollow core fiber Raman wavelength converters are devices enabling to red-shift the wavelength of laser beams delivered by either fixed wavelength or tunable lasers. Most of the reported converters operate in a pulsed regime with

Slowing of pulses to c/10 with subwatt power levels and low latency using Brillouin amplification in a bismuth-oxide optical fiber [PDF]

, 2007
We report the generation of slow light using Brillouin amplification in a short length of highly nonlinear bismuth-oxide fiber. By using just 2m of fiber, we demonstrate a five-fold reduction in group velocity for ~200ns pulses, which we believe to be a ...

Instability and dynamics of two nonlinearly coupled laser beams in a plasma [PDF]

, 2006
We investigate the nonlinear interaction between two laser beams in a plasma in the weakly nonlinear and relativistic regime. The evolution of the laser beams is governed by two nonlinear Schroedinger equations that are coupled with the slow plasma ...
