PY - 2009 DA - 2009// TI - Fiber-coupled nanowire photon counter at 1550 nm with 24% system detection efficiency T2 - Opt. Lett. JO - Optics Letters SP - 3607 EP - 3609 VL - 34 IS - 23 KW - SNSPD AB - We developed a fiber-coupled superconducting nanowire single-photon detector system in a close-cycled cryocooler and achieved 24% and 22% system detection efficiencies at wavelengths of 1550 and 1315 nm, respectively. The maximum dark count rate was ~1000 counts/s. N1 - exported from refbase (https://db.rplab.ru/refbase/show.php?record=679), last updated on Thu, 15 Dec 2011 20:25:42 -0600 ID - Hu_etal2009 ER -
