In one respect,  however, its success has been limited: The instrument, which was  conceived as a "planet hunter", has found planets, but the ultimate  success has - foreseeably - failed to materialise, despite an enormous  amount of observation time. However, 6 years of experience provided  valuable information about the limiting factors, which have now been  reliably identified, as well as possible remedies.  This gave rise to  the idea of a "SPHERE+" upgrade - an improvement in spectral resolution,  as well as an upgrade of the XAO system with a second stage.[[BR]][[BR]]Presentation: German[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/WikiStart/att-sphere_plus.pdf Slides: English][[BR]]Questions: German, English ||

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 ||
