微光学为利用光纤在所需位置有效地变换辐射波前开辟了新的机会。在这里，我们讨论使用微型连接器套件的相对定位的光纤与纳米精度。采用DLW光刻（Direct Laser Writing）的单一工艺制作出套件中的所有光学元件：光纤微连接器和微透镜，解决了光学元件精确对准的关键问题。研究了高耦合效率的微透镜辅助单模光纤。该光耦合套件的进一步改进基于与多芯光纤（MCF）组合的对准的微透镜阵列，其中每个微透镜与其自身的芯直接相对地定位。由于所提出和证明的印刷工艺，可以实现微透镜位置的纳米精度。这种套件显著提高了用于空间分辨光谱学的光学仪器的性能。具有用于每个芯的单独透镜设计的基于MCF的光耦合套件的可能的重要应用之一是实时3D成像。此外，使用这种套件的并行多光束激光加工非常重要。
Microoptics opens up new opportunities for effective transformation of the radiation wavefront at the needed position using optical fiber. Here we discuss the use of a micro-connector kit for relative positioning of an optical fiber with nanometer accuracy. A single technological process of the DLW-lithography (Direct Laser Writing) to create all optical elements of the kit: optical fiber micro-connector and micro-lens, is used to solve the key problem of the precise alignment of optical elements. Micro-lens assisted single-mode fiber with high light coupling efficiency is demonstrated. Further improvement of this light coupling kit is based on aligned micro-lens array combined with multi-core optical fiber (MCF), where each micro-lens is located directly opposite to its own core. Nanometer accuracy of micro-lenses location could be achieved due to proposed and demonstrated printing process. Such kit significantly improves performance of optical instruments for spatially resolved spectroscopy. One of the possible important applications of MCF-based light coupling kit with individual lens design for each core is a real-time 3D-imaging. Moreover, parallel multi-beam laser processing with such kit is of great importance.
