Introduction to Infrared Transceiver Diode

What is an Infrared Transceiver Diode?

An infrared transceiver diode, also known as an infrared LED (Light Emitting Diode) or an infrared photodiode, is a semiconductor device that emits and detects infrared radiation. It is widely used in various applications, such as remote controls, wireless communication, and optical data transmission. In this article, we will explore the basics of infrared transceiver diodes, their working principles, applications, and the future trends in this field.

Working Principle of Infrared Transceiver Diode

The working principle of an infrared transceiver diode is based on the photoelectric effect. When a forward bias voltage is applied to the diode, electrons and holes are generated due to the recombination of charge carriers. When these charge carriers recombine, they release energy in the form of photons. This process is known as electroluminescence, and the emitted light is infrared radiation. On the receiving side, an infrared photodiode converts the infrared radiation into electrical signals. When the infrared radiation falls on the photodiode, it generates a current that can be amplified and processed by electronic circuits. This process is known as photoelectric conversion.
