WebOct 20, 2000 · Modulation Instability (MI) is a process that appears in most nonlinear wave systems. Because of MI, small amplitude and phase perturbations (from noise) grow rapidly under the combined effects of nonlinearity and diffraction (or dispersion, in the temporal domain). As a result, a broad optical beam [or a quasi–continuous wave (quasi-CW ... WebFeb 7, 2024 · 11th class of 207402, this video serves as part of the class hosted at Chiang Mai University.
