Introduction

The infrared photo diode, also known as IR photo diode, is a semiconductor device that converts infrared radiation into electrical signals. As a key component in various fields such as optical communication, remote control, and infrared imaging, it plays an essential role in modern society. This article aims to introduce the industry of IR photo diodes, covering their basic principles, applications, market trends, and future development prospects.

Basic Principles of IR Photo Diode

An IR photo diode is a semiconductor device that consists of a PN junction. When infrared radiation is incident on the PN junction, it can generate an electric current. The conversion process can be divided into three stages: absorption, charge separation, and charge transport.

1. Absorption: Infrared radiation is absorbed by the semiconductor material, leading to the excitation of electrons and holes.
2. Charge separation: Due to the built-in electric field of the PN junction, the excited electrons and holes are separated, forming a charge carrier.
3. Charge transport: The charge carriers are transported to the external circuit, generating an electric current.

The performance of an IR photo diode is mainly determined by its absorption spectrum, responsivity, and noise. The absorption spectrum determines the range of infrared radiation that the diode can detect. The responsivity represents the sensitivity of the diode to infrared radiation, and the noise represents the interference of the diode output signal.
