Effective realization of time domain multiplexing for SSPD arrays is possible due to a short electric pulse of the SSPD as response to radiation quantum absorption, picosecond jitter and extremely low noise equivalent power (NEP). We present experimental results of testing 2{\texttimes}2 arrays in the infrared waveband. The measured noise equivalent power in the infrared and expected for the terahertz waveband is 10 - 21 WHz -1/2 . The best quantum efficiency (QE) of SSPD is 50{\%} at 1.3 {\textmu}m wavelength.", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=1493), last updated on Tue, 18 May 2021 12:57:01 -0500", opturl="https://www.nrao.edu/meetings/isstt/2004.shtml" }
