Waveguides in optical fibers and photonic integrated circuits (PIC) have become an immensely successful innovation. Photonic components offer enormous potential for astronomical instrumentation, as they can reduce the amount of bulky, heavy free-space optics and pave the way for innovative solutions. Such astrophotonic devices are already integrated in high-end instruments, leading to groundbreaking discoveries, e.g. the study of the supermassive Black Hole in our Milky Way using GRAVITY at the VLT (Nobel Prize for Physics 2020). With the ongoing development of novel manufacturing methods and designs, the field of astrophotonics continues to grow.[[BR]][[BR]]At the innovation center innoFSPEC Potsdam, photonic solutions are developed for applications along the signal chain of optical/NIR telescopes, e.g. fiber-based OH-suppression filters (potentially for ELT-MOS/MOSAIC), frequency combs (for STELLA), a PIC-based spectrograph (PAWS), or interferometric beam combiners, also based on PIC (for CHARA). After design, manufacture, and initial laboratory characterization, such components are being prepared for on-sky tests, to validate them for use in real instruments. I will give a brief overview of the astrophotonic research activities at AIP and highlight our current work on beam combiners for stellar interferometry.[[BR]][[BR]]Presentation: German[[BR]]Slides: English[[BR]]Questions: German, English ||
