Abstract
A burst-mode optical amplification apparatus and method is provided. The burst-mode optical amplification apparatus includes a gain saturation signal generator configured to generate a gain saturation signal for gain stabilization based on an incoming input optical signal; a wavelength multiplexer configured to wavelength multiplex the incoming input optical signal and the gain saturation signal; and an optical amplifier configured to amplify both the wavelength-multiplexed input optical signal and the wavelength-multiplexed gain saturation signal. The apparatus may further include a time delay module configured to synchronize the input optical signal and the gain saturation signal by delaying the transmission time of the input optical signal, taking into consideration the processing time needed by the gain saturation signal generator to generate the gain saturation signal.
