Working Principles of Diode IR

The working principles of diode IR technology are based on the photoelectric effect, where electrons are emitted from a semiconductor material when it absorbs photons of light. In the case of IR diodes, these photons are infrared light. The diode's ability to generate or detect IR radiation depends on its composition and structure. To generate IR radiation, a diode is biased in reverse bias mode. When a forward bias is applied, the diode emits IR radiation due to the recombination of electrons and holes in the semiconductor material. The emitted IR radiation's wavelength depends on the material's bandgap energy. For detecting IR radiation, the diode operates in forward bias mode. When the diode absorbs IR photons, it generates a photoelectric current that can be amplified and processed to obtain useful information.
