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…
Characterization of a C-RED One camera for astrophotonical applications
Stella Vješnica, Eloy Hernandez, Kalaga Madhav +1
To better understand the impact of the avalanche gain applied in the detector technology and apply this technology in our in-house astrophotonic projects, we have characterized a C…
Six-telescope integrated optics beam combiner fabricated using ultrafast laser inscription for J- and H-band astronomy
Aline N. Dinkelaker, Sebastian Smarzyk, Abani S. Nayak +6
We have built and characterized the first six-telescope discrete beam combiner (DBC) for stellar interferometry in the astronomical J-band. It is the DBC with the largest number of…
Astrophotonics: photonic integrated circuits for astronomical instrumentation
Martin M. Roth, Kalaga Madhav, Andreas Stoll +6
Photonic Integrated Circuits (PIC) are best known for their important role in the telecommunication sector, e.g. high speed communication devices in data centers. However, PIC also…
