We report the observation of light-enhanced electro-optic spectral tuning in annealed proton-exchanged, asymmetric domain-duty-cycle periodically poled lithium niobate (PPLN) channel waveguides for second-harmonic generation. The spectral tuning rate was increased rapidly from 0.07 nm/(kV/mm) to a saturated value of 0.32 nm/(kV/mm) in a 30%/70% domain-duty-cycle PPLN waveguide when the fundamental pump power near 1534 nm was increased from 0.6 to 46 mW. The second-harmonic laser power at 767 nm was identified to be the source enhancing the spectral tuning.
我们报告了在用于二次谐波产生的退火质子交换、非对称畴占空比周期性极化铌酸锂（PPLN）通道波导中对光增强电光光谱调谐的观察结果。当1534 nm附近的基频泵浦功率从0.6 mW增加到46 mW时，在30%/70%畴占空比的PPLN波导中，光谱调谐速率从0.07 nm/(kV/mm)迅速增加到饱和值0.32 nm/(kV/mm)。767 nm处的二次谐波激光功率被确定为增强光谱调谐的源。
