We discuss the realization of highly efficient fan-out elements. Laser-beam writing lithography is available now for fabricating smooth surface relief microstructures. We develop several methods for optimizing microstructure profiles. Only a small number of parameters in the object plane are necessary for determining the kinoform. This simplifies the calculation of M x N arrays also for large M and N. Experimental results for a 9-beam fan-out element are presented.
我们讨论了高效扇出元件的实现。激光束直写光刻技术目前可用于制造表面光滑的微结构。我们开发了几种优化微结构轮廓的方法。确定相息图仅需要物平面中的少量参数。这也简化了大M和N情况下M×N阵列的计算。文中给出了九光束扇出元件的实验结果。
