Abstract

We demonstrate phase de-multiplexing of QPSK signal to BPSK signals based on dual-pump phase sensitive amplifiers by controlling and stabilizing the gain axis. The de-multiplexed BPSK signals have an OSNR penalty less than 1-dB compared to the back-to-back BPSK signals.

Quadrature Squeezing and IQ De-Multiplexing of QPSK Signals by Sideband-Assisted Dual-Pump Phase Sensitive Amplifiers

Mingyi Gao, Takayuki Kurosu, Karen Solis-Trapala +2 more

High gain extinction ratio and stable control of the phase in phase sensitive amplification are fundamental to realize either phase regeneration or quadrature squeezing of phase modulated signals in an efficient and robust manner. In this paper, we show that a combination of our previously demonstrated “sideband-assisted” dual-pump phase sensitive amplifier with a gain extinction ratio of more than 25dB, and a phase-locked loop based stabilization technique, enable efficient QPSK quadrature squeezing. Its stable operation is exploited to realize phase de-multiplexing of QPSK signals into BPSK tributaries. The phase de-multiplexed signals are evaluated through measurement of constellation diagrams, eye diagrams and more importantly, BER curves. The de-multiplexed BPSK signals exhibited an OSNR penalty of less than 1dB compared to the back-to-back BPSK signals.

Optical QPSK regeneration using dual-pump degenerate phase-sensitive amplification

Jeng-Yuan Yang, Youichi Akasaka, Motoyoshi Sekiya

Optical phase regeneration of QPSK by employing two signal conjugates in a dual-pump degenerate phase-sensitive amplifier is verified via simulations. Phase error standard deviation of 12.827° is reduced to 3.357°. We further verify this scheme's scalability to support 8PSK.

Characterization and Applications of Vector Phase-Sensitive Amplifiers

Abel Lorences-Riesgo

This work is devoted to the characterization of vector phase-sensitive amplifiers and processors. A detailed analysis of degenerate vector phase-sensitive amplifier (PSA) is performed.The gain and phase-sensitive extinction ratio are theoretically analyzed using three-wave theory. Experiments and simulation results confirm the validity of this three-wave theory. The influence of polarization-mode dispersion is also evaluated, showing that aligning the pump polarizations at the fiber input is essential in order to achieve the theoretically predicted results. The scheme is also compared to the degenerate scalar PSA scheme. At the same pump power, the vector PSA has lower gain but also less influence from higher-order idlers and lower pump depletion due to FWM between the pumps. Using the degenerate vector PSA, phase-sensitive (PS) amplification of dual-polarization (DP) binary phase-shift keying (BPSK) signals was demonstrated. To the best of our knowledge, this was the first demonstration of a DP-modulated signal with large net phase-sensitive gain. Furthermore, we also demonstrated that this scheme can phase regenerate the signal. The same scheme was also used for a different purpose: quadrature decomposition into two cross-polarized waves. We demonstrated demultiplexing of quadrature phase-shift keying (QPSK) signal into two cross-polarized BPSK signals by the operating the amplifier in phase-insensitive mode. The design of a novel phase-locked loop scheme enabled stable operation and negligible penalty in the decomposition.

Quadrature squeezing of phase modulated signals

Takayuki Kurosu, Mingyi Gao, Karen Solis-Trapala +1 more

We present two effective methods to perform quadrature squeezing and their experimental demonstrations performed on phase modulated signals. The first method, which is based on phase sensitive amplification, is used for de-multiplexing the two orthogonal phase components of QPSK signals. The second method, which is a hybrid method combining optical parametric processes and amplitude/phase modulation, is used for simultaneous phase regeneration of two coherent WDM BPSK signals.

Optical demultiplexing of a QPSK data channel into two BPSK sub-channels based on phase sensitive amplification

Zahra Bakhtiari

We demonstrate optical demultiplexing of a QPSK signal into two BPSK sub-channels based on coherent vector addition of original signal and the phase conjugated copy respectively. Both sub-channels of a QPSK signal are extracted simultaneously and independently using a scalable phase sensitive amplification technique. This phase sensitive method potentially may also be applied to higher level QAM signals.
