Abstract

The present invention is related to an all-optical OR device embodied by using the gain saturation and wavelength conversion characteristics of semiconductor optical amplifier (SOA), and more particularly, to a technique to embody an all-optical OR gate that performs all-optical logic operation by utilizing optical signals transmitted at arbitrary points of optical circuits such as optical computing circuits as the pump signal and the probe signal.
