Model and Measurements of an Optical Stack for Broadband Visible to Near-IR Absorption in TiN KIDs

K. Kouwenhoven, I. Elwakil, J. van Wingerden +4

Typical materials for optical Kinetic Inductance Detetectors (KIDs) are metals with a natural absorption of 30-50% in the visible and near-infrared. To reach high absorption effici…
