Abstract All optical wavelength converter (AOWC) play important functionalities to enhance the network reconfiguration, efficient wavelength routing and assignment, non-blocking capacity in future dynamic optical access networks. In optical access networks, bandwidth limitation and wavelength continuity constraints lead to inefficient utilization of wavelength resources. AOWCs are the premier option to cope with these network constraints. On the other hand, advanced modulation formats have been extensively analyzed and used to achieve the high spectral efficiency. Since advanced modulation formats are more sensitive to amplitude and phase noise, AOWC are more suitable to achieve minimum power penalty and maximum conversion efficiency. In this paper, AOWC based on four wave mixing (FWM) in highly nonlinear fiber (HNLF) for coherent 100 Gbps dual-polarized differential quadrature phase shift keying (DP-DQPSK) has been designed. The performance of AOWC is optimized at different probe input power, different pump power and wavelength to achieve the maximum conversion efficiency. After the multiwavelength conversion based on 0.7 km HNLF, the power penalty for converted 100 Gbps DP-DQPSK signals is less than 4.15 dB at BER of 10-9 and maximum conversion efficiency of −10.58 dB has been achieved.

基于HNLF中FWM效应的全光波长转换器分析100Gbps相干双极化DQPSK信号

摘要 全光波长转换器(AOWC)在增强未来动态光接入网络的网络重构、高效波长路由和分配、无阻塞能力等方面发挥着重要作用。在光接入网络中,带宽限制和波长连续性限制导致波长资源的低效利用。AOWC 是应对这些网络限制的首要选择。另一方面,高级调制格式已被广泛分析并用于实现高频谱效率。由于高级调制格式对幅度和相位噪声更敏感,因此 AOWC 更适合实现最小功率损失和最大转换效率。在本文中,已经设计了基于高度非线性光纤 (HNLF) 中的四波混合 (FWM) 的 AOWC,用于相干 100 Gbps 双极化差分正交相移键控 (DP-DQPSK)。AOWC 的性能在不同的探头输入功率、不同的泵浦功率和波长下进行了优化,以实现最大的转换效率。在基于 0.7 km HNLF 的多波长转换后,转换后的 100 Gbps DP-DQPSK 信号的功率损失小于 4.15 dB,BER 为 10-9,最大转换效率达到 -10.58 dB。
