InGaAs (indium gallium arsenide) is an important semiconductor material widely used in the field of optoelectronic detection, especially inOutstanding performance in high-speed detection, infrared imaging, and gas analysis
The device has the characteristics of wide spectral response range (400-2600 nm), high quantum efficiency, and miniaturized packaging, and has made significant progress in ultra-thin structure design and technology integration in recent years.
1. Material characteristics and core applications
InGaAs is composed of indium, gallium, and arsenic elements, and its band structure is adjustable, enabling wide spectral detection from visible light to short wave infrared (SWIR). Traditional detectors typically cover wavelengths of 800-1700 nm,Suitable for fiber optic communication, LiDAR, and gas detection (such as CH4, CO2 analysis, H2 hydrogen analysis)The new design extends the response range to 400-2600 nm through structural optimization, enhancing multi scenario applicability.
2. Mainstream product types and packaging
There is a variety of InGaAs detector products in the market, including:
TO5 packaging(2mm diameter): Suitable for industrial grade high-sensitivity detection;
TO-CAN packaging(500 μ m or 1mm photosensitive surface): Small size, low cost, suitable for integrated equipment;
-
TO46 flat window packaging(1mm diameter): Balancing transparency and mechanical strength. Different packaging meets multi-level needs from laboratories to industrial sites, with prices ranging from tens of yuan to tens of thousands of yuan. Shenzhen and other places are the main sales distribution centers.
900nm-2600nm PD detector, the physical picture is as follows:
