Description

Microwave Kinetic Inductance Detectors (MKIDs) were invented in 1999 at
Caltech and JPL with the promise of both high detector sensitivity and
an easy solution to scale into large arrays. Over 20 years of
significant development, MKIDs have fulfilled this promise with their
sensitivity approaching the fundamental limit and the pixel count
reaching 10^5. The technical maturity of MKIDs have brought them broad
applications in astronomical instruments from mm-wave, IR/visible to
X-ray for ground-based, sub-orbital and space missions, as well as
non-astronomical applications such as dark matter search and quantum
information science. In this talk, I will review the technical progress
in the understanding of device physics, the techniques invented for
improving the sensitivity, the implementation of various optical
coupling schemes, the study of materials, and the development of
fabrication process for large arrays, made over the past 20 years.
