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…
