摘要
提出了串联两个迈克尔逊干涉仪来实现多光束干涉的方法。利用该方法在掺铁铌酸锂光折变晶体中制作出了二维的椭圆型光子微结构。使用平面导波图、远场衍射图和布里渊区光谱成像3种手段对二维椭圆型光子微结构的结构特性进行了验证和分析。最后,总结二维椭圆型光子微结构的特性。
A method of cascaded two Michelson interferometers for multi-beam interference is proposed. Using this method, two-dimensional elliptic photonic microstructures can be induced in iron-doped lithium niobate crystal. The structural characteristics of two-dimensional elliptic photonic microstructures were verified by plane wave guiding, far field diffraction pattern imaging, and Brillouin-zone spectroscopy. Finally, the characteristics of two-dimensional elliptical photonic microstructures are summarized.
