Signal power asymmetry optimisation for optical phase conjugation using Raman amplification.
We numerically optimise in-span signal power asymmetry in different advanced Raman amplification schemes, achieving a 3% asymmetry over 62 km SMF using random DFB Raman laser amplifier. We then evaluate the impact of such asymmetry on the performance of systems using mid-link OPC by simulating transmission of 7 × 15 Gbaud 16QAM Nyquist-spaced WDM-PDM signals.
متن کاملDynamical amplification of phase conjugation using a modulated optical feedback in a Nd:YVO4 laser.
We demonstrate an efficient dynamical amplification of phase conjugation in the gain medium of a diode-pumped Nd(3+)YVO4 solid-state laser via excitation of its relaxation oscillations. Consequently, enhancement in the modulated amplitude of the phase conjugate wave is observed with up to +30 dB compared to the classical homodyne approach.
متن کاملPeriodic amplification and conjugation of optical solitons.
Nondegenerate optical parametric amplifiers can be used to simultaneously phase conjugate and amplify a pulse in a nonlinear optical fiber. The gain in the amplifiers compensates the linear loss in the fiber, while the phase conjugation effectively neutralizes second-order dispersion, self-phase modulation, the Raman self-frequency shift, and Gordon-Haus jitter. If the remaining third-order and...

متن کاملTwo Means of Compensating Fiber Nonlinearity Using Optical Phase Conjugation
The growing demand of higher capacity over longer transmission distances has seen fiber nonlinearity as a major limiting factor in modern optical transmission systems [1, 2]. Among the methods under investigation, nonlinearity compensation using optical phase conjugation (OPC) has emerged as an effective means of suppressing the nonlinear impairments [3, 4, 5]. This paper shall discuss two type...
