我们提出了一种可重构的Tbit/s网络开关元件，采用双通硅上液晶（LCoS）技术，伴随着双向简并四波混频（FWM）在一个单一的高度非线性光纤（HNLF）。我们展示了基于LCoS + HNLF的2.3 Tbit/s多功能疏导开关，该开关可同时执行选择性插入/分出、可切换数据交换和功率均衡，用于23通道100 Gbit/s归零差分正交相移键控（RZ-DQPSK）信号。在误码率为10 kHz时，功率均衡的功率损失小于1.5 dB。选择性的单/双通道添加/删除实现与功率损失小于1.2 dB。可切换的两个通道的数据交换和同时的六个通道的数据交换的功率惩罚小于5 dB的实现。
We propose a reconfigurable Tbit/s network switching element using double-pass liquid crystal on silicon (LCoS) technology accompanied by bidirectional degenerate four-wave mixing (FWM) in a single highly nonlinear fiber (HNLF). We demonstrate the LCoS + HNLF-based 2.3-Tbit/s multi-functional grooming switch which performs simultaneous selective add/drop, switchable data exchange, and power equalization, for 23-channel 100-Gbit/s return-to-zero differential quadrature phase-shift keying (RZ-DQPSK) signals. Less than 1.5-dB power penalty is observed for power equalization at a bit-error rate (BER) of 10⁻⁹. Selective single-/two-channel add/drop are achieved with power penalties less than 1.2 dB. Switchable two-channel data exchange and simultaneous six-channel data exchange are implemented with power penalties less than 5 dB.
