An ultra-broadband wavelength conversion is presented and experimentally demonstrated based on nondegenerate four-wave mixing in silicon waveguides. Two idlers can be generated and their wavelengths can be freely tuned by using two pumps where the first pump is set close to the signal and the second pump is wavelength tunable. Using this scheme, a small phase-mismatch and hence an ultra-broad conversion bandwidth is realized in spite of the waveguide dispersion profile. We show that the experimental demonstrations are consistent with the theoretical estimations. Total conversion bandwidth is estimated to reach >500 nm and it can provide a feasible approach to realize one-to-two wavelength conversion among different telecommunication bands between 1300 nm and 1800 nm.
基于硅波导中的非简并四波混频，提出并通过实验演示了一种超宽带波长转换。通过使用两个泵浦可以产生两个闲频光，并且它们的波长可以自由调谐，其中第一个泵浦设置在靠近信号的位置，第二个泵浦的波长是可调的。利用该方案，尽管存在波导色散分布，但仍实现了小的相位失配，从而实现了超宽的转换带宽。我们表明实验演示与理论估计是一致的。总转换带宽估计达到>500 nm，并且它可以提供一种可行的方法来实现1300 nm至1800 nm不同电信频段之间的一对二波长转换。
