论文摘要
我们为第二次谐波生成（SHG）设计，制造和测试的磷化胆碱（GAP）纳米波导。我们使用光学通信O波段中的低功率连续波泵在655 nm左右的可见范围内演示了SHG。我们的结构利用模态相匹配，使得泵的较低阶征量相匹配第二个谐波的高阶本征模。我们通过改变波导的宽度并调整泵的波长，观察到相互作用的相互作用模式的不同组合。提出的结果有助于开发用于经典和量子应用的有效非线性波浪过程的综合光子平台。
We designed, fabricated and tested gallium phosphide (GaP) nano-waveguides for second harmonic generation (SHG). We demonstrate SHG in the visible range around 655 nm using low power continuous-wave pump in the optical communication O-band. Our structures utilize modal phase matching, such that lower order eigenmodes of the pump are phase matched to higher order eigenmodes of the second harmonic. We observe phase matched SHG for different combinations of interacting modes by varying the widths of the waveguides and tuning the wavelength of the pump. The presented results contribute to the development of integrated photonic platforms with efficient nonlinear wave-mixing processes for classical and quantum applications.
