title: Study of differential cross-polarization modulation in a semiconductor optical amplifier.
abstract: Differential cross-polarization modulation (DXPoM) wavelength conversion using a semiconductor optical amplifier has been proposed to outperform substantially traditional cross-polarization modulation (XPoM). This work presents analytical small-signal models of XPoM and DXPoM. The transfer function of DXPoM is used to elucidate the significant improvement in bandwidth and the relationships among the modulation bandwidth, the delay, the operating points and other device parameters of a semiconductor optical amplifier (SOA).
