A new method for stabilizing the bias of an Electro-Optic mach-Zehnder modulator has been developed to maximize the switching extinction ratio in burst mode packet traffic. By sampling and minimizing the off-level output power of the modulator, a high extinction optical gate switch in obtain regardless of the variation of the packet traffic density.
