We report a unique spectral narrowing and manipulation technique in an optical parametric oscillator (OPO) realized by an integrated periodically poled lithium niobate comprising an optical parametric gain medium sandwiched by two electro-optic polarization-mode converters (EO PMCs). We achieved a manipulation of the gain spectrum of the OPO via EO and/or temperature control of the EO PMCs, in which we obtained single to multiple signal spectral peaks from the OPO with a spectral width reduced by up to 10 times and peak intensity increased by up to 6 times in comparison with the original signal. Fast EO tuning of the narrowed signal spectral peak has also been demonstrated.
我们报告了一种独特的光谱窄化和控制技术，该技术在一个由集成周期性极化铌酸锂构成的光参量振荡器（OPO）中实现，该铌酸锂包括由两个电光偏振模式转换器（EO PMC）夹在中间的光参量增益介质。我们通过电光（EO）和/或电光 PMCs 的温度控制来实现 OPO 的增益光谱的控制，在这其中，我们获得了从 OPO 中产生的单到多个信号光谱峰值，与原始信号相比，光谱宽度缩小了 10 倍，峰值强度增加了 6 倍。我们还演示了对缩小的信号光谱峰值的快速电光调谐。
