Spatial dependence of gain nonlinearities in InGaAs semiconductor optical amplifier

Counter-propagating sub-picosecond pulses are used to monitor gain saturation along the waveguide of an InGaAs superlattice semiconductor optical amplifier at 1550nm wavelength. The functional form of the spatial dependence of gain saturation is found to depend on pulse energy. These observations ar...
