laser diode
Quick Summary
A laser diode is a semiconductor device that emits light when an electric current passes through it. These diodes are made from III-V compounds, and their emission wavelength depends on the specific semiconductor compound used.12
Laser diodes are crucial components in various electronic applications. They are used in digital audio and video disc players to read data from discs. Additionally, they serve as light sources in long-distance optical fiber communication systems, transmitting signals efficiently. Unlike gas or optically pumped lasers, semiconductor lasers can be modulated directly at high frequencies, making them highly versatile.342
