Towards High-Throughput Visible Photonic Lanterns for the EMARCOT Project
Abani Shankar Nayak, Julius Goehring, Marina Centenera-Merino +14
Photonic EMARCOT is an innovative project involving Spanish, German and Australian research institutes that aims to integrate multiple Optical Tube Assemblies (OTAs) using photonic…
Demonstration of a multimode-to-multimode photonic lantern for astronomy
Marina Centenera-Merino, Andrew Ross-Adams, Christopher Betters +14
Photonic lanterns have been widely used in astronomy as low-loss multiplexing devices, typically coupling light from a multimode input into several single-mode outputs. In this wor…
Validation and extension of the PAWS Zemax model as a first step in the development of a Compact Arrayed Waveguide Stacked Multi-Object Spectrograph (CAWSMOS)
Fabienne Mangelsdorff, Andreas Stoll, Lars Zimmermann +4
The linear size of a bulk optical astronomical spectrograph scales with the diameter of the primary mirror of the corresponding telescope. As modern telescopes continue to increase…
The Potsdam astroComb (POCO) Part I: Mode crossing effect in feedback resonators
Daniel Bodenmüller, Kalaga Madhav, Martin Roth
We investigate theoretically and experimentally the mode interaction in an integrated Silicon Nitride (Si3N4) microring resonator with interferometric coupling realized by a feedba…
