Infrared transceiver diode, as a key component in the field of infrared communication, plays a vital role in modern electronic devices. This article will provide an in-depth introduction to the infrared transceiver diode industry, covering its definition, working principle, types, applications, and future development trends.

Definition and Working Principle of Infrared Transceiver Diode

Infrared transceiver diode, also known as infrared photodiode, is a semiconductor device that can convert infrared light into electrical signals or vice versa. It is widely used in various fields such as remote control, wireless communication, and optical sensing. The working principle of infrared transceiver diode is based on the photoelectric effect, which is the conversion of light energy into electrical energy.

In the process of receiving infrared signals, the infrared transceiver diode absorbs the infrared light, and the absorbed light energy is converted into electrical energy. Then, the electrical signal is amplified and processed to obtain the original information. In the process of transmitting infrared signals, the infrared transceiver diode converts the electrical signal into infrared light, and the infrared light is emitted to achieve the purpose of communication.

Types of Infrared Transceiver Diode

According to the different wavelengths of infrared light, infrared transceiver diodes can be divided into three types: near-infrared, mid-infrared, and far-infrared. The following is a detailed introduction to each type:

Near-infrared infrared transceiver diode: The wavelength range is about 0.75-1.5μm. It is widely used in remote control, optical communication, and optical storage. The most commonly used near-infrared infrared transceiver diode is the PIN photodiode.

Mid-infrared infrared transceiver diode: The wavelength range is about 1.5-25μm. It is mainly used in infrared imaging, infrared spectroscopy, and thermal imaging. The most commonly used mid-infrared infrared transceiver diode is the MCT photodiode.

Far-infrared infrared transceiver diode: The wavelength range is about 25-1000μm. It is mainly used in thermal imaging, infrared spectroscopy, and remote sensing. The most commonly used far-infrared infrared transceiver diode is the HgCdTe photodiode.
