High Signal-to-Noise Ratio Stimulated Brillouin Scattering Gain Spectrum Measurement

Open Access Open Access

Abstract

A technique to measure nonlinear processes, such as stimulated Brillouin scattering, with a very-high signal-to-noise ratio (SNR) is presented. Brillouin gain measurement with 77 dB SNR is demonstrated over a 2m-long section of single-mode fiber.
