Abstract
Despite the relatively long carrier lifetime of a semiconductor optical amplifier (SOA), all-optical wavelength conversion based on a single SOA at 320 Gb/s has been achieved through a detuned filtering technique [1]. The function of the filter is to convert the probe chirp dynamics into amplitude modulation. Due to the ultra-fast chirp dynamics, this scheme is expected to work at much higher bit rates. In this work we numerically investigate the possibility of all-optical wavelength conversion at 1 Tb/s based on a single SOA and a Gaussian optical bandpass filter.
