In this study, fabricated 320 × 256 infrared focal plane arrays (FPAs) were realised using a GaSb/InAs-based type-II superlattice heterostructure for midwave infrared (MWIR) imaging. We report here the optimized fabrication and characterization of single-pixel infrared detectors and FPAs. MWIR spectral response up to 5 μm of these single-pixel detectors was evident up to 250 K. Responsivity was measured to be 1.62 A/W at 0.8 V and 80 K. Current–voltage characteristics at room temperature (300 K) and at low temperature (18 K) revealed the resistance and dark current variation of the device in the operating bias region. Moreover, good thermal images were obtained at device temperatures up to 150 K for low-temperature targets. Low noise equivalent difference in temperature was measured to be 58 mK at 50 K and 117 mK at 120 K.

High Uniformity

Infrared focal plane arrays (IRFPA) suffer from inherent low frequency and fixed patter noise (FPN). To achieve high quality infrared image by mitigating the FPN of IRFPAs, a novel low-noise and high uniformity readout integrated circuit (ROIC) has been proposed. A correlated double sampling (CDS) with single capacitor method has been adopted in the ROIC design which can effectively reduce the FPN, KTC and 1/f noise. A 4×4 experimental readout chip has been designed and fabricated using the SMIC 0.18 μm CMOS process. Both the function and performance of the proposed readout circuit have been verified by experimental results. The test results show that the proposed ROIC has a good performance in practical applications.
