Abstract

Using a Mach-Zehnder interferometer, we have injected a perturbed Gaussian light beam into a tapered semiconductor optical amplifier. The growth rate of the amplitude of the filamentary perturbation depends on the amplifier gain, its geometry, and the fringe spacing. Numerical solutions of a relatively simple set of ordinary differential equations for the amplitude of a sinusoidal filamentary perturbation in a tapered semiconductor amplifier agree qualitatively with the results.
