利用近场扫描光学显微镜研究了二维三角形光子晶体的光传输特性。通过样品耦合的光强度的空间变化取决于收集光学器件的光子能量和数值孔径。我们讨论了观察到的依赖关系与晶体中光学模式的局域结构之间的关系。通过这种技术可以区分从第一布里渊区内外具有傅里叶分量的模式产生的数据中的特征。
We use a near-field scanning optical microscope to study optical transmission through a two-dimensional triangular photonic crystal. Spatial variations in the intensity of light coupled through the sample depend on the photon energy and the numerical aperture of the collection optics. We discuss the relationship between the observed dependence and the local structure of the optical modes in the crystal. Features in the data arising from modes with Fourier components inside and outside the first Brillouin zone can be distinguished by this technique.
