论文摘要
在这项贡献中，我们回顾了ALSI项目的结果（用于恒星干涉测量法的高级激光编写），旨在评估超快激光撰写的潜力，以制造具有与HI5或PFI（例如HI5或PFI）实现的性能兼容的中型集成光学（IO）设备。 L，L'和M带中等传播损失的波导是在硫化甘露植物和ZBLAN玻璃杯中制造的，用于开发光子构建块以及完整的MID-IR 4 Telescope Beam Combiner。我们讨论了经过测试的组合者的优势和缺点，并讨论了继续这项工作的可能路线图。
In this contribution, we review the results of the ALSI project (Advanced Laser-writing for Stellar Interferometry), aimed at assessing the potential of ultrafast laser writing to fabricate mid-infared integrated optics (IO) devices with performance compatible with an implementation in real interferometric instruments like Hi5 or PFI. Waveguides for the L, L' and M bands with moderate propagation losses were manufactured in Gallium Lanthanum Sulfide and ZBLAN glasses and used to develop photonic building blocks as well as a full mid-IR 4-telescope beam combiner. We discuss the advantages and disadvantages of the tested combiners and discuss a possible roadmap for the continuation of this work.
