Terahertz superconducting kinetic inductance detectors demonstrating photon-noise-limited performance and intrinsic generation-recombination noise

The development of large-format detector arrays with background-limited performance is of particular interest at the terahertz (THz) band, which is a unique band in search of our cosmic origins. With high sensitivity and being more promising in the pixel number and multiplexing technology, supercond...

Description
Summary:The development of large-format detector arrays with background-limited performance is of particular interest at the terahertz (THz) band, which is a unique band in search of our cosmic origins. With high sensitivity and being more promising in the pixel number and multiplexing technology, superconducting kinetic inductance detectors (KID) are emerging as a major choice of detectors of this type. Here we fabricate three-THz-band (0.35/0.85/1.4 THz) KIDs on a single chip from a 120-nm-thick aluminum (Al) superconducting film and measure photon-noise-limited performance and intrinsic generation-recombination noise at high (>1 pW) and low (
