Definition and Basics of Transmitter LED

A transmitter LED is a semiconductor device that emits light when an electric current passes through it. It is composed of a p-n junction, where electrons and holes recombine, releasing energy in the form of photons. This process is known as electroluminescence. Transmitter LEDs are widely used in various applications, including communication, optical data transmission, and medical equipment. The basic structure of a transmitter LED consists of a semiconductor material, typically gallium arsenide (GaAs) or gallium nitride (GaN), which serves as the active region. The semiconductor material is sandwiched between a p-type and an n-type material, forming the p-n junction. When an electric current is applied, electrons and holes are injected into the active region, leading to the emission of light.
