首次在周期性极化MgO:LiNbO3 （PPMGLN）波导中制备并研究了基于级联χ(2)的1.5µm波段波长变换器。在泵浦功率仅为16 mW的情况下，获得了-26 dB的转换效率，这与基于非掺杂衬底的PPLN波长转换器的最高报道值相兼容。对于长度为45mm的器件，3db转换带宽高达68nm。
1.5-µm-band wavelength converters based on cascaded χ(2) in periodically poled MgO:LiNbO3 (PPMGLN) waveguides are fabricated and studied for the first time. A conversion efficiency of -26 dB is obtained with the pump power of only 16 mW, which is compatible with the highest reported value of the PPLN wavelength converters based on nondoped substrates. The 3 dB conversion bandwidth is found to be as large as 68 nm for a 45-mm-long device.
