Single-Photon Detectors for Infrared Wavelengths in the Range 1–1.7 μm

Abstract

The ongoing progress of scientific research in areas such as quantum communications, low-light level laser ranging, and material science (to name but a few) has led to increased interest in the detection of single photons in the wavelength range 1-1.7 μm. Several technologies have been used to detect photons with wavelengths in this range -each with different characteristic parameters that affect their suitability for specific applications. This chapter will provide a review of progress in the development of detectors for use in this spectral region and will highlight some notable results.
