  1. What Is InGaAs?

    InGaAs is an alloy of gallium arsenide and indium arsenide, and is a III-V compound semiconductor. Creating this material is a complicated process, so why go through all the trouble? This article discusses InGaAs in detail and offers benefits for using this technology for SWIR and other imaging applications.

  2. SWIR And The U-2

    The U-2 spy plane is the leading reconnaissance platform for the United States. The camera used in today’s U-2, SYERS, uses electronic sensors to see in both the mid-wave infrared (MWIR) band (thermal energy) and the short wave infrared (SWIR) band (reflected light).

  3. Why SWIR?

    The development of InGaAs sensors has enabled the practicality of using the shortwave infrared (SWIR) spectrum for imaging applications. This article discusses the basics of SWIR imaging, and the benefits of using InGaAs technology and its use with thermal imaging.

  4. The Third Infrared Window

    Long wave infrared (LWIR) and mid-wave infrared (MWIR) sensors and cameras have been used in military settings for detecting human activity through thermal emissions. Using the short wave infrared (SWIR) portion of the spectrum extends unique capabilities that often compliment LWIR and MWIR imaging. 

  5. NIR InGaAs Pixel Chip Fabrication

    InGaAs pixel chips are utilized in products like 2D NIR/SWIR cameras, NIR/SWIR linear arrays, and avalanche photodiodes. This app note presents the process of creating NIR pixel chips, starting at the crystal growth of semiconducting InGaAs on an InP substrate wafer to the product inspection.
