Infrared Photodetector IR2D35W is a high-speed and high-sensitivity detector which is made of AlGaAs/GaAs material. It has a broadband spectral response, wide spectral response range up to 3um, high responsivity and fast response time. It is mainly used in optical communications, fiber sensors, optical remote sensing and spectral sensing. This article will discuss the application field and working principle of IR2D35W.

The IR2D35W detectors have the greatest application potential in the field of optical communications. It can be used to convert the optical signals to electrical signals, such as the signal demodulation, wavelength division multiplexing and frequency division multiplexing. Its wide spectral response range and fast response time make it ideal for various types of optical fiber communication, such as pulse code modulation (PCM) and return-to-zero (RZ).

The IR2D35W detector can also be applied in the field of fiber sensors. It can be used to convert the optical signals into electrical signals for sensing, such as the shape and intensity of the signal or other variations of optical signals. By measuring the changes in the optical power of the input signal, the sensor can acquire and indicate useful information about the environment. In the field of optical remote sensing, it can be used to detect and measure the light intensity and wavelength distribution, which is useful in the identification and quantification of substances.

The IR2D35W detector is also widely used in spectral sensing applications. By measuring the energy level of electromagnetic radiation at different wavelengths, it can be used to identify objects or substances. This is especially helpful in the field of spectroscopy, which is a process of analyzing the composition of substances. In addition, it can be used to observe and analyze the sun’s energy radiation.

The working principle of IR2D35W is based on the photoelectric effect. When the IR2D35W detector receives an light beam, the photons of the light beam excite the electrons in the AlGaAs/GaAs material of the detector. The excited electrons will release energy and move through the detector which generates a current. This current is then amplified and converted into an electrical signal that can be used to measure and analyze the light beam.

In conclusion, the IR2D35W detector has many potential applications in optical communications, fiber sensors, optical remote sensing and spectroscopy. Its wide spectral response range and fast response time make it an ideal choice for various types of applications. Its working principle is based on the photoelectric effect, in which the incident light beam excites the electrons in the AlGaAs/GaAs material of the detector and generates an electrical signal.
