Abstract
We demonstrate an all-optical XOR logic function for 40Gb/s differential phase-shift keyed (DPSK) data signals in the C-band, based on four-wave mixing (FWM) in a silicon nanowire. Error-free operation with a system penalty of ~3.0dB and ~4.3dB at 10⁻⁹ BER is achieved.
摘要
我们基于硅纳米线中的四波混频（FWM），展示了用于C波段40Gb/s差分相移键控（DPSK）数据信号的全光异或逻辑功能。在误码率为10⁻⁹时实现了无差错操作，系统代价约为3.0dB和4.3dB。
