我们展示了热压印技术的可行性，该技术能够构建具有液晶特性的有机薄膜，形成几微米级的特征尺寸。压印技术可以直接应用于包括介电镜在内的各种基材上。如此制造的三维微腔的横向延伸可达20μm，高度在1至5μm之间。示例性地，产生了柱微腔，其中通过形成0D腔模式图案来观察三维光子限制。压印技术进一步有利于形成半球形柱几何形状而不是圆柱形柱，从而产生横向腔模式的等距模式间距。由 AIP 出版社出版。
We demonstrate the feasibility of a thermal imprint technology capable of structuring organic thin films with liquid crystalline properties forming feature sizes on a several micrometer scale. The imprint technique can directly be applied onto a variety of substrates including dielectric mirrors. The so fabricated three-dimensional microcavities have lateral extensions up to 20 mu m and heights between 1 and 5 mu m. Exemplarily, pillar microcavities were produced wherein three-dimensional photonic confinement is observed by the formation of 0D cavity mode patterns. The imprint technique further favors the formation of hemispherical pillar geometries rather than cylindrical pillars, resulting in equidistant mode spacings of transversal cavity modes.
