提出了一种基于硅波导中双泵浦四波混频（FWM）的1310 ~ 1550 nm波段波长转换器。分析了波段间波长转换的原理。对于任意入射信号，通过适当设置两个泵浦波长以完全满足相位匹配条件，可以自由分配转换的空闲波长。仿真结果表明，该信号可以在1310 ~ 1550波段之间灵活转换。由于完全满足FWM相位匹配条件，不同波长信号的转换效率非常稳定。利用这种双泵浦波分复用结构，通过根据波分复用信道间隔设计硅波导的色散分布，还可以实现波分复用信号的信道选择功能。
A wavelength converter between 1310 and 1550 nm bands is presented based on two-pump four-wave mixing (FWM) in a silicon waveguide. The principle of the inter-band wavelength conversion is analyzed. For an arbitrary incident signal, the converted idler wavelength can be freely assigned by suitably setting the two pump wavelengths to completely satisfy the phase-matching condition. Simulation results show that the signal can be flexibly converted between 1310 and 1550 bands. The conversion efficiencies for the signals with different wavelengths are very stable because the FWM phase-matching condition is completely met. Using this two-pump FWM configuration, channel-selective function can also be realized for wavelength division multiplexing (WDM) signals by engineering the dispersion profile of the silicon waveguide according to the WDM channel spacing.
