Scaling laws for multi-object spectrographs: empirical relationships and the photonic advantage of CAWSMOS
Kalaga V. Madhav, Martin M. Roth
The paper analyzes how the mass and cost of multi‑object spectrographs scale with the number of channels and resolving power, and shows that photonic integrated‑circuit designs lik…

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…
