title = "Photonics-Assisted Radio-Frequency Self-Interference Cancellation and Fiber Transmission Using a DP-QPSK modulator",
abstract = "A photonic approach for radio-frequency (RF) self-interference cancellation and fiber transmission using a dual-polarization quadrature phase-shift keying (DP-QPSK) modulator is proposed in this paper. One dual-parallel Mach-Zehnder modulator (DP-MZM) in the DP-QPSK modulator is used to cancel the interference signal directly in the optical domain via optical carrier-suppressed double-sideband modulation, whereas the other DP-MZM in the DP-QPSK modulator provides a phase-tunable optical carrier. The two interference-free optical sidebands and the phase-tunable optical carrier at the two orthogonal polarization states are combined for the recovery of the desired RF signal. Since the interference is directly cancelled in the optical domain, the fiber dispersion will not lead to the reappearance of the interference signal, which makes it suitable for long-distance fiber transmission. An experiment is performed. RF self-interference cancellation is demonstrated both in single-carrier and wideband operations at 9 and 15 GHz, and the compensation of the fading effect is also studied.",
