We demonstrate conversion from 64 × 10 Gbit/s optical time-division multiplexed (OTDM) data to dense wavelength division multiplexed (DWDM) data with 25 GHz spacing. The conversion is achieved by time-domain optical Fourier transformation (OFT) based on four-wave mixing (FWM) in a 3.6 mm long silicon nanowire. A total of 40 out of 64 tributaries of a 64 × 10 Gbit/s OTDM-DPSK data signal are simultaneously converted with a bit-error rate (BER) performance below the 2 × 10(-3) FEC limit. Using a 50 m long highly nonlinear fiber (HNLF) for higher FWM conversion efficiency, 43 tributaries of a 64 × 10 Gbit/s OTDM-OOK data signal are converted with error-free performance (BER<10(-9)).
我们展示了从64×10 Gbit/s光时分复用（OTDM）数据到具有25 GHz间隔的密集波分复用（DWDM）数据的转换。该转换通过基于3.6毫米长硅纳米线中的四波混频（FWM）的时域光学傅里叶变换（OFT）实现。64×10 Gbit/s OTDM-DPSK数据信号的64个支路中共有40个同时被转换，误码率（BER）性能低于2×10^(-3) FEC极限。使用50米长的高非线性光纤（HNLF）以实现更高的FWM转换效率，64×10 Gbit/s OTDM-OOK数据信号的43个支路被无差错转换（BER<10^(-9)）。
