中文摘要 本文提出了一種新型的多波長全光再生方案,利用相位時鐘光纖光參量放大,並採用相鄰信道偏振正交的方法,實現對由異步信源產生的雙波長信號全光再生.理論分析了參量放大中的增益飽和現象用於幅度噪聲抑制,以及利用相位時鐘及後續色散實現對信號定時的機理.在這個基礎上,對兩個獨立信源產生的異步雙波長10Gbit/s信號進行再生實驗,實驗表明該方案有效的抑制了基於多波長3R再生系統中信道間的四波混頻與交叉相位調製等非線性干擾.系統在單波長和雙波長情況下分別將兩路信號信噪比改善了至少6.5dB與4.5dB.誤碼率測試結果說明,與背對背測試結果相比,無論是在單波長還是雙波長條件下,兩路波長的信號經過再生後都實現了約2dB的接收機功率代價的改善.
英文摘要 [With the continued development of the wavelength division multiplexing (WDM) network,there arises an urgent demand for the research of multi-wavelength all-optical 3R regeneration. In this paper,a novel multi-wavelength alloptical regeneration scheme has been proposed. Using phase clock in the fiber-optic parametric amplification and polarization multiplexing, all-optical regeneration of dual-wavelength signals generated by two independent WDM transmitter is realized. Theoretical analysis is carried out for the operation mechanism of the amplitude noise suppression using the gain saturation of the parametric amplification,and re-timing using phase modulation with cascading dispersion. Dual-wavelength 10 Gbit/s signal optical regeneration is demonstrated experimentally. Experimental results show that the inter-channel nonlinearities like four-wave mixing and cross phase modulation are effectively reduced. In the single and dual-wavelength cases, signal to noise ratio improvements of at least 6. 5 dB and 4. 5 dB have been achieved, respectively,after regeneration. Bit error rate test shows that about 2 dB power penalty improvement is obtained in both single- and dual-wavelength operations.]
