In this paper, the all‐optical realization of a logic OR gate using gain saturation in a standard semiconductor optical amplifier (SOA) is successfully experimentally demonstrated. This reported feasibility study shows the all‐optical OR function can be easily achieved with an extinction ratio of about 7 dB. © 2003 Wiley Periodicals, Inc.
