We will review the development in the last decade of discrete beam combiners (DBC), phase sensors based on the propagation of light in photonic lattices. The latest results on the development of DBC for astronomical applications will be presented, al

Publikováno v: SPIE Proceedings.

Photonic technology has pushed the limits of astronomy ever more in recent years. Especially, integrated optics (IO) has led to new standards in accuracy and stability in the field of astronomical interferometry where several beams need to be cohere

Towards 3D-photonic, multi-telescope beam combiners for mid-infrared astrointerferometry

Autor: Jan Tepper, Lucas Labadie, Stefan Nolte, Thomas Pertsch, Romina Diener, Stefano Minardi

In the past two decades high precision optical astronomical interferometry has benefited from the use of photonic technologies. Today, near-infrared interferometric instruments deliver high-resolution, hyperspectral images of astronomical objects and

Fringe tracking at longer wavelengths is advantageous for its larger Fried parameter (R 0 ) and longer coherence time (τ 0 ). The fringe trackers which are currently available at the VLTi (Finito, FSU, Gravity, etc.) tracks fringes at the near infra
