Abstract

We describe a new type of FIR detector based on lumped element superconducting resonators (LEKIDs). Thesedevices can act as distributed FIR radiation absorbers without the need for an additional coupling structure.In addition, these devices can be integrated into a compact filled array geometry with high filling factor. Wedescribe the optimization of lumped element resonators for high coupling efficiency to incoming radiation in thewavelength region from 200μm - 450μm, measurements of electrical and optical properties of these devices andthe design of a prototype array using these detectors.
