The proposed devices would be useful in numerous applications. The use of GaN would have the advantage over HgCdTe of allowing simultaneous detection in the UV and IR with a single detector. This would eliminate many difficulties in developing pixel-collocated detector arrays covering both bands. A multiband detector can be used as a remote thermometer by using the spectral information from the difference in the signals for the two bands. In applications such as mine detection, the use of images in two different spectral bands can aid in the detection and reduce the number of false positives. The UV portion of the detector could be used to detect muzzleflash to locate the position of enemy troops, while the IR range is useful for determining troops and functional vehicles and armored cars, etc. The proposed device would have the ability to produce separate images of the psectral ranges or a single cmbined image. This would be a significant improvement on the current systems using two separte detector arrays. Although GaN intraband devices are still in the early stages of development, the proposed detector would be highly relevant in other device efforts such as a GaN QWIP or QCL.
