Abstract
A two-electrode semiconductor optical amplifier that has two sections and two separated electrodes is proposed for an all-optical wavelength converter. Pattern effect reduction based on dynamic gain compensation is theoretically investigated using a time-domain model that takes into account the carrier diffusion process between the two sections, and the Q factor of the converted light is calculated to evaluate pattern effects. Simulation results show that the Q factor is greatly improved when the section lengths and the currents are appropriately selected.
