A linear array of avalanche photodiodes (APDs) comprising of 128 pixels was fabricated from InAs. The uniformity of the dark currents and avalanche gain was investigated at 77, 200 K and room temperature. The array shows highly uniform results apart from some defective pixels at the edge of the arrays. At 200 K and at a wavelength of 2.04 µm, we obtained an unmultiplied responsivity of 0.61 A/W at 0 V, along with a gain of 8.5 at a bias of 10 V.
