Abstract The chapter covers photodetectors for photons in the optical and near UV range (about 200 nm to 700 nm). Important for particle and astroparticle experiments are photodetectors which detect light generated in scintillation or Cherenkov detectors, for example.

The use of nanowires and nanowire structures as photodetectors is an emerging research topic. Despite the large amount of reports on nanowire photoresponse that appeared in the literature over the last decade, the mechanism leading to high photosensitivity and photoconductive gain in high aspect ratio nanostructures has been elucidated only recently ...

Abstract This chapter starts by introducing the characteristics common to all photodetectors. Detector efficiency, noise, detectivity, and bandwidth are among the several key performance characteristics considered. Then several materials systems and the spectral ranges they cover are introduced.

Photodetectors and photodetector arrays for optical processing
SPIE Proceedings, 1992Photodetector arrays and architectures for optical processing, including acousto-optical (AO) signal processing applications such as spectrum analysis, for which the demands on photodetector arrays are substantially greater than for typical image sensing applications, are discussed.

This paper is intended as a status report on high-speed detectors for the visible and near-infrared portion of the optical spectrum. Both vacuum and solid-state detectors are discussed, with the emphasis on those devices which can be used as direct (noncoherent) detectors of weak optical signals modulated at microwave frequencies.
