This paper describes a unique and high-performance 1024-element linear In(subscript x)Ga(subscript 1-x)As/InAs(subscript y)P(subscript 1-y) detector array for environmental sensing applications in the 1 micrometers to 2.6 micrometers spectral range. The detector array was fabricated using hydride vapor phase epitaxy grown material. The size of each pixel of the detector array is 13 X 500 micrometers (superscript 2) with 25 micrometers pitch. Improvements in dark current and quantum efficiency were realized by optimization of crystal growth, thermal annealing, and diffusion techniques. Transmission electron microscopy analysis of the fabricated structure was used to find the effect of thermal annealing on the dislocation density and the leakage current. The measured results of the 1024-element detector array sliver is presented.
