Abstract

Infrared (IR)detectors have an important role in looking at objects from a different perspective to investigate less-evident properties. The advances in IR-detector technologies led to the need for the single-photon detectors. Single-photon detectors (SPD) are ultra-low-noise devices with increased sensitivity that are able to detect a minimum energy quantum of light. These SPDs can sense and count individual photons and can be utilized in many emerging applications in which the only available signal is on the order of several photons. There is a provision for IR detectors to build a device that can create an adequate signal-to-noise ratio. To achieve this, the detector should efficiently absorb light at a particular wavelength. It should have noise lower than the signal and should be coupled with read-out electronics that have similar low-noise properties.
