Abstract
This work presents the results of the development and fabrication of sensitive and ultrafast detectors based on thinfilm superconducting nanostructures: hot-electron bolometers (HEBs) and visible and infrared superconducting singephoton detectors (SSPDs). The main operational principles of the superconducting devices are presented as well as the technology of fabrication of the detectors and their main types and parameters. The achieved record parameters of the detectors allow application of the fabricated devices to solution of various research problems in the near, middle and far IR ranges
