Abstract: The six-polarization shift keying quadrature (6PolSK-QPSK) has been proved to be an alternative to four-dimensional (4D) modulation scheme. A variety of transmission compensation schemes have been developed for 24-Point 6PolSK-QPSK combining the advantages of polarization… read more here.

Abstract: We numerically investigate phase-sensitive amplification of a quadrature phase shift keying (QPSK) signal in a 35 µm dispersion engineered silicon-graphene oxide hybrid waveguide. The four-wave mixing efficiency is effectively enhanced by exploiting the ultrahigh Kerr… read more here.

Abstract: The aggregation and de-aggregation between one QPSK and two BPSK signals are experimentally demonstrated based on cross-phase modulation (XPM) effects and phase-sensitive amplification (PSA), aiming to improve flexible spectral efficiency in the elastic optical network.… read more here.
