چکیده
A phase sensitive amplification (PSA) regeneration model for M-ary shift keying (MPSK) signals with amplified spontaneous emission (ASE) noise based on the interference between signal and its (M+1)th harmonic is proposed. Compared existing models different combinations of harmonics, new optimal in theory to deal MPSK degraded by ASE noise. The QPSK format taken as an example simulation verification two classic are also performed same parameters comparison. performance evaluated input–output constellations, amplitude factors, relay distance at bit error rate (BER) 3.8×10?3 measuring transmission reach after regenerator. results show that has ASE-noise format, which promising be applied large-capacity, flexible, reliable optical transport networks.

All optical signal level swapping and multilevel amplitude noise mitigation based on different regions of optical parametric amplification.
All optical signal level swapping and multilevel amplitude noise mitigation are experimentally demonstrated using the three gain regions of optical parametric amplification, i.e., linear, saturation, and inversion. The two-amplitude-shift-keying and eight-quadrature-amplitude-modulation optical communication systems with baud rates of both 10 and 20 Gbaud have been employed to demonstrate the p...

Simultaneous demultiplexing and regeneration of 40-Gb/s optical time division multiplexed (OTDM) signal based on self-phase and cross-phase modulation in a dispersion shifted fiber is numerically and experimentally investigated. The optimal walkoff time between the control pulse and OTDM signal is obtained by numerical simulation. Our experiment also shows that it is an effective method for rea...
متن کاملSimultaneous all-optical phase noise mitigation and automatically locked homodyne reception of an incoming QPSK data signal.
Simultaneous phase noise mitigation and automatic phase/frequency-locked homodyne reception is demonstrated for a 20-32 Gbaud QPSK signal. A phase quantization function is realized to squeeze the phase noise of the signal by optical wave mixing of the signal, its third-order harmonic, and their corresponding delayed variant conjugates, converting the noisy input into a noise-mitigated signal. I...
متن کاملAll-optical regeneration of differential phase-shift keying signals based on phase-sensitive amplification.
All-optical regeneration of differential phase-shift keying signals based on phase-sensitive amplification is described. Nearly ideal phase regeneration can be achieved in the undepleted-pump regime, and simultaneous amplitude and phase regeneration can be realized in the depleted-pump regime.
متن کاملPhase noise mitigation of QPSK signal utilizing phase-locked multiplexing of signal harmonics and amplitude saturation.
We demonstrate an all-optical phase noise mitigation scheme based on the generation, delay, and coherent summation of higher order signal harmonics. The signal, its third-order harmonic, and their corresponding delayed variant conjugates create a staircase phase-transfer function that quantizes the phase of quadrature-phase-shift-keying (QPSK) signal to mitigate phase noise. The signal and the ...
