摘要
在这篇文章中，我们介绍了定制的后焦平面（BFP）扫描光谱仪，用于探索二维（2D）光子晶体（PhC）中的角度分辨光色散，该晶体由纳米级电介质棒的六边形晶格构成。我们利用毛细力光刻技术制作了一个 1 厘米 x 0.5 厘米的均匀大面积光子晶体，其特点是在金层上形成了基于聚合物的六边形晶格。这种精确度实现了光子模式的有效约束，从而增强了光学相互作用。通过直接扫描 BFP，我们成功绘制出了角度分辨反射光谱图，揭示了该结构与角度相关的光学响应，并深入了解了其等频轮廓。我们的方法简化了对先进光学材料的探索，凸显了精确制造和测量技术在理解和利用结构材料的光学特性实现各种技术应用方面的作用。
Back-focal plane scanning spectroscopy for investigating the optical dispersion of large-area two-dimensional photonic crystal fabricated by capillary force lithography
In this article, we introduce our custom-built back-focal plane (BFP) scanning spectroscopy to explore an angle-resolved optical dispersion in two-dimensional (2D) photonic crystal (PhC) constructed with hexagonal lattice of nano-scaled dielectric rods. We fabricated a uniformly large-area photonic crystal measuring 1 cm by 0.5 cm, featuring a polymer-based hexagonal lattice on a gold layer, using capillary force lithography. This precision enables the effective confinement of photonic modes, leading to enhanced optical interactions. We successfully map out the angle-resolved reflectance spectra by directly scanning BFP, revealing the structure's angle dependent optical response and providing insights into its iso-frequency contours. Our approach simplifies the exploration of advanced optical materials, highlighting the role of precise fabrication and measurement techniques in understanding and utilizing the optical properties of structured materials for various technological applications.
