基于四波混频 (FWM) 和交叉增益调制 (XGM) 的波长转换首次在 1550 nm InAs-InP 量子冲刺半导体光放大器中进行了实验演示。演示了具有依赖于失谐方向的对称转换效率的连续波 FWM 和 FWM 介导的短脉冲波长转换。使用 XGM，我们成功实现了超过 10 THz 的短脉冲波长转换以及超过 7.5 THz 的 2.5 Gb/s 数据序列的无差错数据转换。脉冲 XGM 实验表明，不均匀展宽的增益谱内的相邻区域部分耦合，这增加了操作带宽，但以速度为代价。
Wavelength conversion based on four-wave mixing (FWM) and cross-gain modulation (XGM) is experimentally demonstrated for the first time in a 1550-nm InAs-InP quantum-dash semiconductor optical amplifier. Continuous-wave FWM with a symmetric conversion efficiency dependence on detuning direction and FWM mediated short-pulse wavelength conversion are demonstrated. Using XGM, we have successfully implemented short-pulse wavelength conversion over 10 THz and error-free data conversion of a 2.5-Gb/s data sequence over 7.5 THz. The pulsed XGM experiments suggest that adjacent regions within an inhomogeneously broadened gain spectrum are partially coupled which increases the operational bandwidth, but at the expense of speed.
