abstract="This paper presents an ultrafast niobium nitride (NbN) superconducting single-photon detector (SSPD) with an active area of 3{\texttimes}3{\thinspace}{\thinspace}$\mu$m2 that offers better timing performance metrics than the previous SSPD with an active area of 7{\texttimes}7{\thinspace}{\thinspace}$\mu$m2. The improved SSPD demonstrates a record timing jitter (<25{\thinspace}{\thinspace}ps), an ultrashort recovery time (<2{\thinspace}{\thinspace}ns), an extremely low dark count rate, and a high detection efficiency in a wide spectral range from visible part to near infrared. The record parameters were obtained due to the development of a new technique providing effective optical coupling between a detector with a reduced active area and a standard single-mode telecommunication fiber. The advantages of the new approach are experimentally confirmed by taking electro-optical measurements.",
