Extinction ratio enhancement by sinusoidal phase modulation and nonlinear spectral focusing
To cite this version: Frederic Audo, Christophe Finot. Extinction ratio enhancement by sinusoidal phase modulation and nonlinear spectral focusing. Abstract. We propose a new approach to enhance the extinction ratio of a pulse impaired by a coherent continuous-wave background. Taking advantage of a sinusoidal phase modulation followed by a nonlinear spectral focusing and an optical bandpass filtering, we are able to significantly decrease the level of the unwanted background.
