The optical properties of microlens arrays may be significantly affected by the optical crosstalk effect between adjacent lenses. Recently, this issue has triggered increasing attention in the scientific community. In this study, an integrated microlens array (MLA) consisting of self-aligning convergent waveguides of microlenses was fabricated. The optical crosstalk effect does not influence the performance of such system. Based on the self-focusing effect principle, self-writing of the waveguide array was achieved in a photosensitive polymer. The light collection and guiding performance of the MLA with and without thermal cross-linking treatment was analyzed in depth. The relation between the stray light and the filling rate of the MLA shows that a high filling rate decreases the optical crosstalk. Finally, an integrated MLA with a large area, high uniformity, and excellent optical performance was fabricated.

制造微透镜阵列自对准会聚波导以收集和引导光

微透镜阵列的光学特性可能会受到相邻透镜之间的光学串扰效应的显着影响。最近，这个问题引起了科学界的越来越多的关注。在这项研究中，制造了由微透镜的自对准会聚波导组成的集成微透镜阵列（MLA）。光学串扰效应不会影响此类系统的性能。基于自聚焦效应原理，在光敏聚合物中实现了波导阵列的自写。深入分析了有无热交联处理的MLA的聚光和导光性能。杂散光与MLA填充率之间的关系表明，高填充率会降低光学串扰。最后，一个大面积的集成式MLA，
