Abstract

An all-optical read only memory utilizing cross gain modulation in semiconductor optical amplifiers (SOAs) has been demonstrated for the first time to our knowledge. In our demonstration, an all-optical 2-to-4 line decoder constructed with SOAs has been employed for the construction of this all-optical read only memory. Storing four characters in an American standard code for information interchange (ASCII) format has been successfully carried out. Each character consisting of seven binary bits could be read out at a rate of 10 Giga characters per second.
