Abstract:
A method comprising:micro-fabricating a pixelless thermal imaging device for up-converting a sensed 2-dimensional M/FIR image into a 2-dimensional image in the NIR to visible spectrum, the step of micro-fabricating comprising the steps of: providing a first substrate, the first substrate having a surface suitable for subsequent crystal growth; crystallographically growing on the surface of the first substrate a plurality of layers forming an integrated QWIP-LED wafer; patterning an integrated QWIP-LED wafer forming a device mesa, the device mesa approximately comprising an active area of the thermal imaging device, the active area being approximately the size of the 2-dimensional image in the NIR to visible spectrum; and, isolating material defects in the active area of the QWIP-LED using a laser in order to reduce the effect of the material defect on the operation of the QWIP-LED.
