多光楔板制作大面积光折变光子微结构
|
摘要
提出了一种制作大面积光子微结构的简便方法,利用多光楔板产生大面积的多光束干涉,在光折变晶体中制作出了大面积的周期性光子微结构和准周期性的光子准晶微结构。该方法简便易行,系统稳定性好,无须复杂的调节装置,制作效率高。使用导波强度图像、远场衍射图样、布里渊区光谱成像等方法对制作的大面积光子微结构进行了验证和分析。设计不同的多光楔板,可以制作出多种更复杂的大面积光子微结构。通过适当的处理,制作的大面积光子微结构可以长久地固定在光折变晶体中,也可以擦除后用于制作新的结构,这在集成光学和微纳光子器件领域具有良好的应用前景。
A convenient approach to fabricate large area two-dimensional photonic microstructures was experimentally demonstrated. Large area multi-beam interference was generated by multiple optical wedges board. Large area periodic photonic microstructures were quasi-periodic quasicrystal microstructures were fabricated in a photorefractive crystal. This method was easy to operate,with high stability and production efficiency,without complicated equipment. The induced large area microstructures were analyzed by plane wave guiding,far-field diffraction pattern imaging,and Brillouin-zone spectroscopy. By designing different multiple optical wedges boards,the method were easily extended to generate other more complex large area photonic microstructures. With proper treatment,the large area photonic microstructures is fixed in the photorefractive crystal for a long time,and is also erased and used to make new structures. The proposed method has a good application prospect in the field of integrated optics and micro-nano photonic devices.
