Photosensors or photodetectors are sensors of light or other electromagnetic energy.[1]

Types[edit]

Frequency range[edit]

In 2014 a technique for extending semiconductor-based photodetector's frequency range to longer, lower-energy wavelengths. Adding a light source to the device effectively "primed" the detector so that in the presence of long wavelengths, it fired on wavelengths that otherwise lacked the energy to do so.[4]
