Three-dimensional complete photonic-bandgap materials offer unique opportunities regarding the integration of optical waveguide architectures in three dimensions. However, corresponding experimental realizations are truly sparse. Here, we fabricate such waveguides using direct laser writing and a silicon double-inversion procedure. The optical characterization is in good agreement with theoretical calculations, raising hopes that even more complex architectures may soon come into reach.
三维完全光子带隙材料在三维光波导结构的集成方面提供了独特的机会。然而，相应的实验实现却非常稀少。在这里，我们使用直接激光写入和硅双反转工艺来制造这种波导。光学特性与理论计算吻合良好，这让人们对制造更复杂的结构充满了希望。
