| Abstract: | As a Ⅲ-Ⅴ semiconductor material, In1-xGaxAs can response from 0.87μm (GaAs) to 3.5 μm (InAs) by tuning the relative amount of Gallium in the alloy. With the wide applications in the area of optical communication, the related researches in InGaAs infrared Focal Plane Array (FPA) are also attracting huge interests due to the advantage of RT working conditions. There are several commercialization products related to InGaAs FPA in international market, applied to military, aviation and space remote sensing area etc. The main characteristics and recent progresses of In1-xGaxAs short IR FPA detectors are introduced. The tendency that the response cutoff wavelength of InGaAs-based detectors is extended to the visible range is focused. |
