Working Principle of Infrared Beam Diode

The infrared beam diode consists of a semiconductor material, typically gallium arsenide (GaAs), which emits light when an electric current passes through it. The following steps describe the working principle of an infrared beam diode: 1. Forward Bias: When a forward bias voltage is applied to the diode, the free electrons and holes are injected into the depletion region, which is the region where the charge carriers are depleted due to the built-in electric field. 2. Recombination: The free electrons and holes recombine in the active region of the diode, releasing energy in the form of photons. The energy of the photons depends on the bandgap of the semiconductor material, which determines the wavelength of the emitted light. 3. Emission: The emitted photons have wavelengths ranging from 700 nm to 3 μm, which fall within the infrared spectrum. The infrared beam diode is designed to emit light at specific wavelengths, which can be tailored to meet the requirements of different applications. 4. Collection and Detection: The emitted light is collected by an optical lens or fiber optic cable and directed towards the desired application. In some cases, the infrared light is detected using photodiodes or phototransistors, which convert the light into an electrical signal.
